                 Power and data transmission 
 The reliable transmission of data and power forms a central foundation of modern electrical and electronic systems. In virtually all areas of application – from industrial automation over information and communication technology to automotive and medical technology – high-performance, low-interference transmission links are of crucial importance. Both wired and wireless technologies are used, each presenting specific advantages, challenges and requirements. 
 The following diagram provides an illustrative overview of the various transmission networks in an industrial environment: 
     Figure 1 – Overview of industrial networks, as of 2025  
 Wired transmission methods such as traditional copper cables, coaxial cables and fibre-optic cables have been used successfully for decades. Single Pair Ethernet (SPE) in particular has recently been gaining in importance, especially in industrial automation and in building and vehicle technology. SPE enables data transmission over just a single twisted pair and, in combination with Power over Data Line (PoDL), allows the simultaneous transmission of data and electrical power. In other application areas, standards and protocols such as Ethernet, CAN, USB, HDMI or Powerline (PLC) are widely used and enable high data rates, robust communication and flexible system architectures. 
 At the same time, wireless technologies are becoming increasingly important. Radio-based systems such as Wi-Fi, Bluetooth, NFC and mobile communications standards, as well as contactless power transfer methods based on inductive or resonant principles, enable new applications and a high degree of flexibility. At the same time, these technologies place increased demands on electromagnetic compatibility, as they are particularly sensitive to interference and can themselves act as sources of interference. 
 However, as transmission frequencies, data rates and power densities increase, so too do electromagnetic interference, line attenuation, crosstalk and radiation. 
 Interference suppression through the use of ferrites 
 Against this backdrop, the suppression of interference and the shielding of data and power transmission lines play a central role. Ferrite components have established themselves as tried-and-tested passive components for attenuating high-frequency interference, suppressing common-mode interference and reducing electromagnetic emissions without significantly compromising the integrity of the useful signals. In doing so, they make an important contribution to compliance with electromagnetic compatibility requirements and, in particular, facilitate the achievement of regulatory limits for conducted and radiated emissions. At the same time, they contribute to greater functional reliability of electronic systems by reducing interference-induced impairments to signal transmission and increasing robustness against external electromagnetic influences. These positive effects are significant in numerous technical fields of application, particularly in medical technology, industrial automation and in telecommunications and communications technology, where both high operational reliability and compliance with strict EMC requirements are essential. Furthermore, specially shaped ferrite components can often be integrated into existing systems in such a way that the geometry and mechanical design of the overall system are altered only slightly, which further facilitates their practical implementation. 
 In the context of data and power transmission, ferrites and related EMC measures can broadly be divided into two main applications: the  suppression  of high-frequency signals in wired transmission paths, and the  shielding  of wireless transmission links against unwanted electromagnetic coupling. Both functions are based on different physical principles and objectives. 
 Suppression of RF signals in wired systemsen 
 In wired transmission lines, high-frequency interference components frequently occur alongside the desired useful signals. These arise, for example, from steep switching edges in power electronics, from switched-mode DC/DC converters, or from electromagnetic coupling from adjacent lines. Ferrite components are used here specifically as frequency-dependent impedances. 
 Interference suppression ferrites act like a choke with low inductance. At high frequencies, the component behaves like an inductor with high losses and high reactive resistance. They have a low quality factor. The losses required in this application prevent resonance with parasitic and line capacitances. Conversely, inductors with a high quality factor are not well suited as interference filters. 
 A ferrite can be described electrically as a complex impedance: 
   Z(f) = R(f) + jX(f)   
 Where: 
  Z(f):  the complex impedance  R(f):  the real part (loss component/resistive)  X(f):  the imaginary part (reactive component/inductive) 
 Both components, R(f) and X(f), are highly frequency-dependent. 
 &amp;nbsp; 
 The imaginary part X(f) 
 At low frequencies, the ferrite behaves mainly like an inductor: 
   X L  = 2 π f L   
 An electric current generates a magnetic field in the ferrite’s inductance. In this process, energy is cyclically stored in the magnetic field and released again; it is not dissipated. The useful signal is hardly attenuated. In unfavourable cases (e.g. in conjunction with capacitance), this can lead to resonance and thus to an increase in the interference signal. 
 The real part R(f) 
 As frequency increases, magnetic losses such as hysteresis losses and eddy current losses occur. These lead to an increasing real part of the impedance. In the real part of the impedance, RF interference energy is converted into heat and removed from the signal path. This allows resonance effects to be suppressed. 
 The frequency-dependent interaction 
 At low frequencies, the ferrite is predominantly inductive. This results in low attenuation of the interference signal. At medium frequencies, the resistive component of the impedance increases sharply. This is where the maximum attenuation of the RF interference signal occurs. Energy is absorbed and converted into heat. At very high frequencies, parasitic capacitances come into play. The magnetic effect of the ferrite decreases. The impedance drops. 
 Ferrites provide better interference suppression than ideal coils, as they have a high loss component. The RF energy is not reflected but dissipated. This prevents resonances and is extremely important in terms of EMC. 
 The following diagram illustrates the frequency responses of Z, R and X for the Neosid ferrite material F02: 
     Figure 2 – Impedance as a function of frequency for ferrite material F02 (MnZn)  
 Complex permeability 
 The reason for the effective interference suppression provided by ferrites lies in their complex permeability: 
   μ = μ‘ – jμ“   
 Where: 
  μ:  the complex permeability  μ‘:  the storage inductance component X  μ“:  the loss component or real part R 
 As frequency increases, μ” grows and attenuation increases. 
 In practical terms, this can be summarised as follows: ferrite is not an ideal inductor, but a lossy HF resistor whose loss component increases with frequency. 
 The following graph shows, by way of example, the frequency-dependent characteristic curves for μ‘ and μ“ for the Neosid ferrite material F02: 
     Figure 3 – Complex permeability as a function of frequency for the ferrite material F02(MnZn)  
 Ferrites are particularly effective at suppressing common-mode interference, as this is often responsible for unwanted radiation. Ferrite cores or beads placed along cables increase the common-mode impedance without significantly affecting the differential signal path. At low frequencies or with DC voltage, they have virtually no effect. 
 Ferrite decoupling elements enable compliance with EMC limits and stabilise signal quality, particularly with high-speed protocols such as Ethernet or Single Pair Ethernet. 
 Shielding of wireless transmission links 
 In wireless transmission methods, signals are transmitted via electromagnetic fields. The challenge here lies not so much in reducing conducted interference, but rather in controlling and limiting the field distribution. Ferritic materials are used for magnetic shielding in this application. Due to their high magnetic permeability, they specifically influence the magnetic field distribution by focusing, deflecting or attenuating field lines 
 This is equally important in inductive or resonant energy transfer systems, which utilise alternating magnetic fields. Here, ferrites reduce stray fields, minimise losses and reduce unwanted coupling to neighbouring electronic assemblies. At the same time, they help to limit electromagnetic emissions and increase immunity to external fields.. 
 One example of this is the inductive transmission path used in contactless charging for various vehicles. Passenger cars, e-bikes or other mobile vehicles can be conveniently and efficiently supplied with energy using this technology. 
     Figure 4 – Simulation of a transmission coil for the inductive charging of an electric vehicle (EV)  
 In summary, ferrites serve both to provide frequency-selective attenuation of unwanted RF interference in wired systems and to specifically influence electromagnetic fields in wireless transmission links. They therefore represent a central element of modern EMC-compliant system designs. 
 Neosid – Your specialist for custom-fit ferrites 
 As a manufacturer of soft magnetic ferrites, Neosid is able to tailor ferrite components specifically to the electromagnetic and mechanical requirements of modern data and power transmission systems. The design is always application-oriented and takes into account both the physical mechanisms of interference suppression and the geometric constraints of the respective application. 
 The starting point for electromagnetic design is the analysis of the relevant frequency spectrum. Depending on whether the ferrites are used to suppress conducted high-frequency interference or to influence magnetic fields in wireless transmission links, material systems with defined complex permeabilities (μ’ and μ’’) are selected from a wide range of different materials. For RF interference suppression, the focus is on a high loss factor in the target frequency range in order to effectively attenuate interference currents and convert them into heat. For shielding and field-guiding applications, on the other hand, high permeabilities and low losses are paramount in order to direct magnetic field lines in a targeted manner and reduce stray fields. 
 The geometric design of the ferrite components takes place in parallel with the material selection. The shape, wall thickness and effective cross-section are dimensioned in such a way that the desired impedance or magnetic effect is achieved without generating undesirable saturation effects or resonances. In wired applications, for example, closed or split cores, sleeves or multi-hole geometries are used to achieve maximum common-mode impedance with minimal impact on the useful signal. For wireless power transfer systems, flat or segmented ferrite structures are being developed that can be optimally integrated into the installation space and support a homogeneous field distribution. 
 To validate the design, Neosid uses numerical simulation methods, such as electromagnetic field simulations and equivalent circuit models, supplemented by material- and component-specific measurements. Prototypes are characterised under real operating conditions to validate attenuation, losses and thermal behaviour. Through this close integration of material development, geometric design and metrological verification, Neosid is able to provide customised ferrite solutions that reliably meet both EMC requirements and mechanical and thermal constraints.

                 Advantages of inductive charging 
 Inductive charging offers a wireless alternative to conventional charging infrastructure for electric vehicles. It offers a number of additional advantages over conductive charging with plugs. The use of charging cables is completely eliminated, making the charging process much more convenient and user-friendly. In addition, inductive charging stations can be installed at central points in the traffic area – for example, in front of traffic lights or at bus stops – to efficiently use every moment a vehicle is stationary to charge its battery. 
 With dynamic inductive charging (in-motion charging), electric vehicles are even supplied with electrical energy wirelessly while driving. For this purpose, transmitter coils are installed in the road surface, which generate a high-frequency magnetic field. Receiver coils installed in the vehicle couple this field contactlessly and convert it into electrical energy, which is either used directly for propulsion or to charge the vehicle battery. Energy is transferred as needed and in segments, so that only the sections of the road that the vehicle is travelling on are activated. This reduces range limitations, allows for smaller battery capacities and significantly increases both the efficiency and comfort of electric mobility. 
     Picture 1: Inductive charging of a car  
 Normative specifications 
 The coil system used for inductive charging of passenger cars is defined, for example, in the SAE standard J2954. The defined coils consist of windings, aluminium shielding plates and an electromagnetically conductive ferrite layer. 
 In previous approaches, standard ferrite tiles were used for this ferrite layer. Due to its high density, the ferrite layer contributes significantly to the weight of the coil system. It is therefore desirable to reduce the volume and mass of the ferrite layer used. 
 OptGeoFerrit joint project 
 We have acquired this knowledge as part of a joint project with the Institute for Electrical Energy Conversion (IEW) at the University of Stuttgart. Based on an evaluation of ferrite masses in power applications, we have created the possibility of investigating complex ferrite structures in a simulation. This enables us to design the ferrite layer precisely and specifically for the application. This allows targeted optimisation of the electromagnetic properties, so that both high efficiency and minimal energy losses can be achieved. 
 As a developer and manufacturer of soft magnetic ferrite cores, we have dealt extensively with this topic. In order to minimise internal system losses, it is necessary to have in-depth knowledge of the behaviour of ferrite components in these applications. 
 In the joint project, we first determined the quality and power loss values of our ferrite compounds as a function of magnetic saturation. We then transferred this material-specific data to simulation software. The three-dimensional design of the ferrite cores can be varied in this software, resulting in geometries that take into account the field distributions in the core. This results in ferrite cores that are optimally adapted to the respective transmission system and in which magnetic hotspots are avoided. The ferrite cores are segmented wherever demanding mechanical requirements would cause particular stress on the core. 
     Picture 2: Simulation model of a charging coil  
 The result is a coil system that makes optimum use of the available installation space. The material used in the form of ferrite compound and coil wire corresponds exactly to the amount necessary to ensure proper functioning. 
 As part of the joint project, the ferrite compound used was reduced by around 30% without compromising functionality. The resulting significant weight savings offer a clear advantage, particularly for the receiver antenna integrated into the vehicle, as they have a positive effect on installation space, system efficiency and the overall vehicle weight. The project investigated an AC charging system for passenger cars with a maximum charging power of 22 kW. However, the findings can be transferred to inductive charging systems for other applications and power ranges. 
 NEOSID – Your partner for custom-fit ferrite cores 
 Our many years of expertise in the design, simulation and manufacture of ferrite cores enable us to precisely implement highly specialised geometries. Using an injection moulding process, we manufacture ferrite cores exactly to the requirements of the respective customer application. Even wall thicknesses of only 0.2 mm can be reliably achieved. The overall mechanical tolerance of the sintered ferrite components is typically ±2%, which guarantees maximum precision. For optimal adaptation to a wide range of applications, we have a portfolio of over 15 specially developed ferrite materials at our disposal, allowing for tailor-made material selection and maximum performance. 
 From core to coil 
 As specialists in wound inductors, we offer our customers not only the development of the right ferrite core, but also the complete manufacture of the associated coil. We develop wound products according to customer-specific requirements and manufacture them on machines specially tailored to our processes. Our technologies enable us to process all common wire types – from the finest enameled wire to thick strands. Production facilities, manufacturing aids and testing technology are developed and manufactured in-house, ensuring maximum precision, flexibility and quality. Our production capacities range from individual prototypes to large series, enabling us to reliably cover both development projects and industrial production volumes.

 Areas of application for inductive charging 
 In addition to inductive charging of electric cars, this technology is suitable for numerous other applications, e.g. e-bikes, e-scooters, drones, medical devices and industrial equipment. 
 The advantages at a glance: 
   Convenience and user-friendliness   
 No need to plug in or unplug cables – simply position and charge. Ideal for places where charging is frequent, e.g. parking spaces. Reduces cable clutter and wear on connectors. 
   Less wear and tear for longer service life   
 No mechanical contacts → less wear and tear. Dustproof and waterproof devices possible, as there are no open charging sockets. 
   Safety   
 No open electrical contacts – ideal for wet and industrial environments. 
   Design freedom   
 Devices can be designed to be completely closed (without connections). Better sealing against water and dust (e.g. protection class IP68). 
   Automated charging   
 Ideal for autonomous vehicles and/or robots. 
   Low maintenance   
 No moving parts, low risk of failure.

                 Product overview and possible applications 
 Summary 
 Planar transformers enable compact, efficient and thermally optimised solutions for modern power supplies. Their layered structure offers advantages such as low stray inductance, high power density and excellent EMC properties. This white paper shows why planar technology plays a key role in applications with limited installation space and high efficiency requirements – from industry and automotive to medical technology. 
 Introduction 
 At a time when power electronics must become increasingly compact, efficient and thermally robust, conventional transformer solutions are increasingly reaching their limits. Planar transformers offer a sustainable alternative here: they combine a space-saving design with high power density and excellent thermal behaviour. 
     Figure 1: Classic transformer       Figure 2: Planar transformer  
 This white paper introduces our new product group of planar transformers, which have been specially developed for use in modern power electronic systems – from industrial applications and charging infrastructures to demanding automotive environments. 
 As a long-standing supplier of customised transformer solutions, we combine technological innovation with proven development and manufacturing expertise. The aim of this document is to demonstrate the advantages and possible applications of planar transformers in a practical manner and to introduce our product solutions. 
 Product group overview 
 This new product group comprises planar transformers in the power class from 1 Watt to 10 Kilowatts output power. Depending on the application, operating voltages up to 1,000V are covered. With a suitable design and appropriate materials, insulation voltages of up to 4,500V can be achieved. The flexible design of planar transformers allows the integration of multiple windings and functional units to reduce wiring effort and assembly space. Operating frequencies range from 50Hz to 1 MHz. In addition to standard ferrite cores, we also use customer-specific cores, which are developed by us according to specifications and manufactured in-house.

 Our product solutions 
 We manufacture our planar transformers in a wide variety of designs and sizes. We use different winding configurations depending on the number of turns and power class. 
 A typical feature of planar transformers is that the windings are realised on a printed circuit board. Two-layer and multilayer printed circuit boards are used for this purpose (see Figure 3). Alternatively, the individual windings can also be made of foil or classic winding wire. 
     Figure 5: Copper foil winding       Figure 6: Copper flat wire winding  
 As a manufacturer of soft magnetic ferrites, we supply the core material for high-performance planar transformers. Our ferrite cores can be customised for specific applications – for maximum efficiency, optimised thermal properties and maximum design freedom. This enables us to provide tailor-made solutions for transformers that are precisely matched to the requirements of modern electronic systems. 
 We manufacture our ferrite cores from a total of 17 specially developed materials based on nickel-zinc (NiZn), manganese-zinc (MnZn) or composite materials. These material systems have been specifically developed for different areas of application in order to enable optimum magnetic properties for inductive components – across different power classes, temperature ranges and operating frequencies. 
 In addition to the classic dry pressing process, we also use a special injection moulding process. This allows the production of complex geometries and offers maximum flexibility in shaping – ideal for making optimum use of the available installation space in demanding applications. 
 Typical applications / use cases 
 Planar transformers are primarily used in applications where compact designs, high power density, good thermal properties and low stray inductance are required. They are preferred in power- and space-critical applications. 
  Here is an overview of typical areas of application :  
  Industry  
 Planar transformers offer high reliability and EMC-compliant design in confined spaces. This makes them particularly suitable for switching power supplies in machine controls, DC/DC converters for automation systems, compact DIN rail power supplies or power supplies for high-frequency welding systems. 
  Automotive  
 Space-saving solutions with high thermal load capacity are required here. Possible areas of application for planar transformers include on-board chargers (OBC), DC/DC converters in electric and hybrid vehicles, power electronics for driver assistance systems (ADAS) or HV/HV isolation in traction systems. With operating temperatures between -40 and +155°C, our planar transformers are also suitable for installation in the engine compartment. Many of our transformers meet the requirements of AEC-Q200. 
  Medical technology  
 With their low height, good insulation properties and reliable heat dissipation, planar transformers are particularly suitable for use in medical technology. Applications here include power supplies in imaging devices (e.g. MRI, CT), examination devices with galvanic isolation and laboratory equipment with special safety requirements. 
  Renewable energies  
 High efficiency over a wide operating frequency range and good EMC properties play a particularly important role here. Planar transformers are used in DC/DC converters in photovoltaic inverters, battery management systems (BMS) and power supplies in wind turbines. 
  Telecommunications / Data centres / Servers  
 With their flat designs, high packing density and suitability for parallel power architectures, planar transformers are ideal for Power over Ethernet (PoE), power supplies for servers, switches and routers, and as DC/DC converters in uninterruptible power supplies (UPS). 
  Aerospace / Railway technology / Defence and security  
 Planar transformers offer decisive advantages in these applications, particularly in terms of reliability, robustness, space savings and thermal efficiency. Due to the high demands in these applications (e.g. shock, vibration, extreme temperatures, electromagnetic interference), classic transformer solutions are often too bulky or insufficiently stable – this is where planar transformers come into their own. They are used in power supplies with extreme requirements in terms of weight, volume and reliability, as well as for galvanically isolated signal and power transmission. 
 Our expertise &amp;amp; development competence 
 The development of planar transformers requires comprehensive technical expertise from various specialist areas. This includes, above all, electromagnetic design and simulation in order to precisely optimise winding design, inductance values and stray losses. Equally important is thermal design, which ensures efficient heat dissipation concepts and the selection of suitable materials. 
     Figure 7: Electromagnetic simulation with ANSYS Maxwell  
 In-depth knowledge of soft magnetic materials and insulation materials forms the basis for high-performance, reliable transformers. Neosid has over 90 years of experience in this field and offers a wide range of suitable materials. This is complemented by knowledge of printed circuit board technology, as planar transformers are often designed as PCB-based components and require a special high-frequency and high-current layout. 
 CAD-supported component design results in stable housings and mounting variants that function reliably even under harsh conditions. Manufacturing expertise and quality assurance are crucial for controlling series processes and ensuring high product quality. 
 In addition, knowledge of relevant standards, safety requirements and certifications is important, as is a deep understanding of system integration and application requirements. Interdisciplinary collaboration and clear communication with customers, manufacturing and development teams round off our competence profile. 
 Conclusion 
 The use of planar transformers offers customers a number of key advantages – in technical operation as well as in product design and manufacturing. Thanks to their compact and flat design, planar transformers enable space-saving integration into modern devices while offering high power density. The flat design supports particularly efficient heat dissipation, which means that thermal stress can be reliably controlled even in performance-critical applications. 
 Another technical advantage is the low stray inductance, which leads to higher efficiency and improved EMC behaviour. Since the windings are manufactured in the form of printed circuit board structures, the components are highly reproducible – an important factor for series production and applications in the high-frequency range. 
 As a customer, you benefit from Neosid&#039;s high design flexibility in development and design: we enable tailor-made solutions for specific requirements.

 1-axis transponder coils in various sizes and designs are successfully used in electronic circuits for contactless identification, positioning systems, sensor technology and for representing communication interfaces, e.g. in RFID technology or access control systems. 
 A ferrite core developed and produced by NEOSID is used as the winding core for the transponder coils. We can choose from over 15 different ferrite materials. Depending on the application, nickel-zinc (NiZn), manganese-zinc (MnZn) or a composite material is used. With our highly developed injection moulding process, we create ferrite core geometries that are optimally designed for their field of application. 
 The entire core of the axial components consists of softmagnetic ferrite material. This results in components with very high efficiency and a high inductance-to-volume ratio. This technical advantage is particularly important in miniaturisation, for example in RFID transponders or medical devices. 
 An overview of the entire product family is provides by the product information  X/Y/Z-, 3D RFID transponder antennas for LF and HF bands .

                 Advantages of contactless transmission technology 
 Inductive transmission systems are used in many applications in our daily lives to increase the convenience and safety of electrical devices. As a practical example, we all know the electric toothbrush or the electric shaver. These devices are used in an environment where contact-based electrical connections reach their limits. In environments with moisture, cleaning agents and other substances, energy transmission via mechanical contacts is unfavorable and such systems cannot be expected to have a long service life. With contactless designs, encapsulated devices can be created that function reliably in critical environmental conditions over the long term. They also offer increased protection for the operator against all hazards that naturally emanate from electrically operated devices. 
 Applications with inductive energy transfer systems 
 Inductive energy transmission systems offer decisive advantages in various applications. The following examples show the broad applicability of this technology in various product areas: 
 In  industrial robots , inductive transmission systems enable a continuous supply of energy and data to robot arms in production facilities without mechanical restrictions. 
 Medical devices such as  pacemakers or insulin pumps  benefit from contactless energy transmission by supplying these systems with electrical energy without invasive interventions. 
 Rotating  camera systems or surveillance cameras  can function uninterruptedly with inductive energy transmission systems as they are continuously supplied with energy. A direct cable connection is not required. 
 In modern  vehicles , rotating components such as steering wheels or sensors are supplied with energy and data by inductive transmission systems. 
 In  wind turbines , the rotors can be supplied with reliable and maintenance-friendly control information using inductive systems. 
     Bild 1 – Basic structure of an inductive energy transfer system  
 Wireless transmission system with pot core coils 
 A stationary energy transmission system can be constructed, for example, with two pot core coils. In this system, the coupled ferrite pair consists of NEOSID pot cores Sch14. The transmitter and receiver coils are shown in the figures below: 
     Picture 2 - Primary/transmitting coil       Picture 3 - Secondary/receiver coil  
 The transmitting and receiving coils are mechanically and electrically separated from each other, e.g. by encapsulating them separately in housings. The separation of the two coils creates an air gap between the two ferrite cores. The air gap leads to a reduction of the coupling factor in the transmission system and increases the magnetic leakage field and thus the leakage inductance. In this Sch14 ferrite system, the maximum air gap is around 2.6 mm. Above this value, the two coils no longer couple with each other or the magnetic field of the transmitter coil runs outside the receiver coil and no more energy can be transmitted. 
 The encapsulation of the receiver coil is shown as an example in the following figure: 
     Picture 4 - Secondary/receiver coil in the housing  
 For demonstration purposes, we have set up a system consisting of a transmitting and receiving coil. The transmitting coil is installed in a housing. An electronic circuit generates an alternating voltage which is applied to the transmitting coil to transfer energy. 
     Picture 5 - Stationary energy transmission system consisting of transmitter and receiver coil in the housing  
 The maximum transmittable power in such a transmission system depends on the maximum permissible current density. The diagram below shows the measured temperature behavior of a winding in the Sch14 ferrite system at an operating frequency of f=100kHz. This diagram can be used to determine the maximum current density for a desired operating temperature. 
     Figure 6 - Temperature behavior and operating current  
 It is interesting to know the maximum power that can be transmitted by the system depending on the air gap between the coils. This is shown as an example for this transmission system at an operating frequency of 100kHz and a maximum coil temperature of T=60°C: 
     Picture 7 - Output power with different air gaps  
 Rotating energy transfer system with special designed cores 
 In many energy transmission systems, it is necessary to transmit significantly more power to the secondary side than is possible with the aforementioned system of standard pot cores. In addition, it is often necessary to integrate the coil system - consisting of transmitting and receiving coils - into a customer-specific device. One example of such a system is the rotating energy transmission system, which can be used in motors, signaling devices or sensors. Here, the secondary side is integrated into a component that performs a continuous rotary movement (rotor). The fixed outer coil part (stator) couples electrical energy into the rotor. Such a system is suitable for the contactless transmission of energy and data. The transmission system does not contain any mechanical contact elements such as sliding contacts. Without mechanical contacts, there is no abrasion and the service life and reliability of the device are significantly increased. 
     Picture 8 - Rotating energy transmission system, stator       Picture 9 - Rotating energy transmission system, rotor  
 Both coils 
 
 Stator/transmitter/primary coil 
 Rotor/receiver/secondary coil 
 
 are also designed as ferrite core coils in this case. For this special geometry, we use ferrite cores that have been tailored precisely to this application. A special injection molding process enables us to design the ferrite cores in such a way that mechanical, electrical and electromagnetic requirements are met. The result is an effective and space-saving transmission system that can be individually adapted to the ambient conditions. 
 A closer look at the arrangement of the coil system shows the following views: 
     Picture 10 – Coil system of the rotating energy transmission system (rotor and stator)       Figure 11 - Section through rotating energy transfer system  
 We can also carry out electromagnetic simulations for such systems with special ferrites in order to check the theoretical feasibility of a specification. 
     Picture 12 - Simulation model of a rotating energy transmission system  
 We have also set up this system and integrated it into a transportable housing to illustrate its function. 
     Picture 13 - Rotating energy transmission system consisting of stator and rotor in housing  
 This inductive energy transmission system is equipped with a fixed air gap. Depending on the operating frequency, the following power data can be tapped on the secondary side: 
     Picture 14 - Output power of a rotating energy transmission system  
 The energy transmission systems shown are examples of how such systems can be constructed. Due to the fact that we develop and produce the ferrite cores, they can be created in a wide variety of geometries. 
 Customer-specific component designs are our specialty! Thanks to our special injection molding process for ferrite cores, we produce custom-fit components for your application - individually according to the defined task and exactly in the specified installation space.

                  In RFID applications, it is often advantageous that the antenna centre axis is aligned at an angle of 90° to the PCB surface.&amp;nbsp; In this case we speak of Z transponder coils. Based on our proven SMD inductor Ms 42, we have now also designed this component for use as an HF RFID transponder antenna.&amp;nbsp;  
     Picture 1: Ms 42 HF RFID transponder antenna       Picture 2: Ms 42, dimensions (mm)  
 &amp;nbsp; 
 For this purpose, a core material is used which is particularly suitable for use at an operating frequency of 13.56 MHz. This results in optimal magnetic and electrical properties for operation as a transponder antenna.&amp;nbsp; 
 Due to the one-piece antenna core, this compact design has excellent mechanical properties, especially high resistance to vibration and mechanical shock. The entire component family meets the requirements of the reliability tests according to AEC-Q200. 
 With the different input capacities of RFID ICs, transponder antennas with adapted inductance values have to be used so that the overall circuit can be operated at a resonant frequency of 13.56 MHz. The following inductance values are currently available: 
     Table 1: Z transponder antenna Ms 42, current delivery programme

 Passive HF/NFC RFID transponders 
 In the product segment of passive HF/NFC RFID transponders, NEOSID offers a wide range of solutions: 
     Picture 3: Overview of the product range of passive HF/NFC RFID transponders  
 &amp;nbsp; 
 These products are passive stand-alone RFID transponders or RFID chips. For communication between a reader and the transponders, these are placed in the electromagnetic field of the reader antenna. Energy and data transmission are contactless.&amp;nbsp; 
 Overall, the following equivalent circuit diagram results for a passive RFID transponder: 
     Picture 4: Passive RFID transponder, equivalent circuit diagram  
 &amp;nbsp; 
 The oscillating circuit components required for a passive RFID TAG are built up as follows:&amp;nbsp; 
 The  oscillating circuit capacitance C in   is usually realised inside the integrated circuit. There is no discrete capacitor outside the RFID IC. This makes it possible to create transponders with very small mechanical dimensions. The capacitance values are shown in the data sheet as input capacitance C in . Depending on the RFID IC used, there are different capacitance values between 15 and 100 pF. 
 The  oscillating circuit inductor L  works as the antenna of the transponder. In NEOSID transponders, it consists of wound enamelled copper wire. The inductor is designed as an air coil or with a ferrite core - this optimises the magnetic properties of the antenna and, among other things, achieves high reading ranges with a compact design. The beginning and end of the winding are connected to the RFID IC at two contact pads. See pictures above! 
 The operating voltage generated at the transponder resonant circuit is used for energy and data transmission between the reader and the  RFID IC . There are HF RFID ICs from various manufacturers in different designs and with different functionalities.&amp;nbsp; 
 The following table provides an overview of known HF RFID ICs. 
     Table 2: Overview of commercially available HF RFID ICs (not complete)  
 &amp;nbsp; 
 The table shows2 with which values of C in  the various HF RFID ICs are available and which corresponding antenna inductance must be used to operate the input resonant circuit at a resonance frequency of 13.56 MHz. 
 &amp;nbsp; 
 Discreetly constructed RFID transponders 
 Alternatively, a passive RFID transponder can also be constructed with discrete components mounted on a printed circuit board. For this purpose, components in correspondingly suitable designs/housings are used. In such a case, inductive components in axial or radial design can be used for the transponder antenna: 
     Picture 5: RFID transponder antenna Ms 42 (radial/Z-design)&amp;nbsp;       Picture 6: RFID transponder antenna Ms 2046 (axial/ X- and Y-design)

 Application examples for discrete RFID transponders 
 To illustrate possible applications for discrete RFID transponders with axial or radial transponder inductances, we have described two common use cases below. 
  Application example 1: eol programming  RFID technology is used for other applications besides the design of passive transponders. One example is the use for so-called end-of-line(eol) programming of electronic devices. In this case, electronic devices are manufactured and even packaged in the production process without any final configuration or programming having been carried out. In a final manufacturing step, an RFID interface built into the device is then used to wirelessly import this configuration or even software components into the device. This procedure has the process-technical advantage that the devices can be manufactured independently of the final programming. Special variants of the units can thus be created at a very late stage of production, allowing the production of common parts to be bundled. Finally, device variants are differentiated using different software during eol programming.

 &amp;nbsp; 
  Application example 2: Energy harvesting  In energy harvesting using RFID technology, small amounts of energy are generated and made available to electronic consumers. The electromagnetic field of a reader antenna acts as the energy source. If the passive RFID transponder is placed in the magnetic field, the electronic circuit in the transponder generates an electrical voltage from it, which is made available to consumers on the transponder side. This enables battery- and mains-independent operation of electronic circuits. Applications for such devices are, for example, medical implants with very low power consumption that are to remain in the body for a longer period of time or permanently.&amp;nbsp;

                  NFC- Smartphone readable: NeoTAG ®  Label MF/F2108  
 This new type of transponder was developed specially for applications where it is not possible to use one of our proven  NeoTAG ®  transponder  in Inlay, Plug or Flag versions due to the design requirement of the object. There are versions available for use with metallic and non-metallic objects. Depending on the required installation of the adhesive film transponders, different compositions can be realized with ferrite layers as the bottom or top layer. On non-metallic objects, there is no need for the ferrite film, thus creating very flat transponders. The outer dimensions can be adjusted variable to meet the application space requirements. 
 Due to its flexible design, this label transponder can be applied to both curved and bent surfaces. 
 Unlike label transponders with antenna layers made of aluminium or copper, this transponder uses an antenna layer of wounded copper wires. This produces significantly better electrical properties with regards to the electric quality factor and the effective antenna surface.&amp;nbsp; 
 Compared to the other NeoTAG transponder designs, the larger antenna surface offers particularly exceptional read properties when combined with mobile end devices such as smartphones.

                 Background 
 Cable networks such as lightning conductors on buildings or earthing networks in industrial production facilities are subject to various changes over their service life which reduce their ability to function. Wear and tear, ageing and renovations can result in these circuits no longer being able to fulfil their protective function. These changes often go unnoticed. Their impact can be serious, for example if a lightning strike is no longer conducted via the intended protection circuit but via the systems that require protection. The result will be damage to plants and systems or faults which lead to sensitive production losses. 
     Picture 1: Connection in a lightning conductor network       Picture 2: Earthing point in an industrial plant  
 &amp;nbsp; 
 &amp;nbsp; 
 Signal transformer by NEOSID 
 NEOSID has developed a special signal transformer for these applications which feeds an electromagnetic pulse into a cable network via a primary winding. 
   
 This network of cabling can, for example, be a network of various sections of a lightning conductor for a building, but could also represent an earthing network e.g. for an industrial manufacturing cell. The arrangement and type of the network requiring monitoring is user-defined. The insertion point of the transformer into the network is also user-defined. The signal is fed and transmitted by a first coil to the cable network. The second coil receives the signal transmitted via the cable network and transfers a measurement value to the evaluation unit. The evaluation unit compares the incoming and outgoing signal and saves a measurement result or displays it so that it can be noted down. If, for example, the transfer resistance at the contact points of the mains network changes over the course of time and in operations, this results in a change to the electrical values and the measurement result deviates from the original value. When a set tolerance is exceeded, the system reports a fault or sets off an alarm. Suitable evaluation circuits are developed by our customers using our signal transformer. Monitoring systems are either fitted to the network for a system check or remain permanently installed in the network for the purposes of ongoing controls. By including the evaluation device in a fieldbus network or a mobile data network it enables remote warning concepts to be implemented, making seamless monitoring possible without the need for on-site manning by service personnel. 
 &amp;nbsp; 
 The advantages of our solution 
 The special feature of the new signal transformer is the fixed positioning of transmitting and receiving coils to one another as a compact, electronic component. This ensures that the reciprocal influence of the directly coupled coils is constant, simplifying the evaluation and processing of the desired signal. In addition, the use of sophisticated shielding of the coils against one another using specially moulded, soft magnetic ferrite elements significantly reduces the parasitic influences. This is particularly important if the measurement devices as described above are possibly only installed for a system check and perhaps once a year at that. The fixed arrangement then helps to keep the sources of faults in the measurement system to a minimum. 
 &amp;nbsp; 
 The goal 
 The goal is to detect changes to the cable network and therefore a decreasing ability to protect the object against electrical shock (lightning protection on buildings) or transition resistances in an earthing network (earthing protection in production facilities) and carrying out repairs in terms of predictive maintenance before damage occurs. 
 &amp;nbsp; 
 Advantages of NEOSID signal transformers: 
 
 Compact design as a single coherent unit consisting of signal transmitter and receiver 
 High decoupling of sending coil to receiving coil 
 THT or SMD version 
 Customer-specific design on request

                 Powerline communication (PLC), or powerline for short, also known under the manufacturers’ designations PowerLAN or HomePlug AV, is a technology which enables existing electrical lines in the low voltage grid to be used for a local data transmission network, instead of additional cabling. It is especially popular in private, where it is used to spread the internet signal in homes. 
   
 Powerline is already used by lots of devices that are connected to each other via the power supply system, for example telephones, alarm systems and CCTV cameras. Home automation and the internet of things are also suitable applications, due to the low data volumes involved. It can also be used for controlling an intelligent power network, or ‘smart grid’. 
 In e-mobility, devices such as the charging station and the vehicle are connected by cable in order to charge. Thanks to powerline, the charging cable can also be used to transfer data, in order to exchange technical parameters, check authorisations and transfer billing data. In these applications, bidirectional data communication is realised according to the EN ISO 15118 series of standards and supports vehicle-to-grid applications. The protocol used is the HomePlug Green PHY standard, which is a simplification of the HomePlug AV protocol standard.&amp;nbsp; This considerably reduces the performance requirements on the control processor, which leads to a significantly reduced power dissipation of the system. 
 &amp;nbsp;  
 &amp;nbsp; 
  Circuit diagram of a PLC transformer  
 In order to couple the data signal into the power line, inductive transformers are used, which usually have one winding each for the transmit and receive signal and one winding for the mains line. Depending on the chipset and the mains voltage range, different turns ratios are required. The desired transmission is as low-loss as possible in the used frequency range. 
     1:1:1 PLC transformer       1:1 PLC transformer  
  Small design and large bandwidth  
 Components for high-frequency transmission are being miniaturised more and more. Additionally they should guarantee high signal quality. At the same time, high safety requirements with large clearance and creepage distances and high insulation voltages are placed on communication technology devices, for example in the standards DIN EN 60664, 60950 and 62368. 
 Powerline transformers from NEOSID are available in various designs. All designs are suitable for automatic assembly and reflow as well as vapour phase soldering. 
 By using special winding arrangements and materials, reinforced and double insulation with voltage strengths of several kilovolts are also possible. A thorough quality inspection ensures compliance with the high requirements. 
  PLC transformers for mains voltage applications  
 Depending on the operating voltage of the carrier network for a Powerline data transmission, there are different requirements for the insulation of the windings in the transformer. If the operating voltage is at mains voltage level (e.g. 230VAC), special requirements are placed on the insulation voltage and the clearances and creepage distances. 
 Our PLC transformer in the RM-R6 housing offers a customised design for these applications, which meets the insulation requirements with the smallest dimensions.&amp;nbsp;

  PLC transformers for low voltage applications  
 In the low voltage range, PLC transformers with a turns ratio of 1:1:1 are generally used. Due to the lower insulation voltage requirements, more compact designs can be realised.
