What influence do changes in ambient temperature have on the resonance frequency of the NeoTAG® transponders?

Our product range of NeoTAG® HF RFID transponders/ RFID chips is constantly being expanded and new transponder versions are regularly added. In connection with the use of our transponders, we have compiled a large amount of background information on mounting, function, design, operating behaviour, etc. due to the many applications in which the products are used. As a supplement to our Product Information HF RFID Transponder data sheet, this article contains further technical explanations and application-supporting information.


With changing the ambient temperature, there are deviations in the natural resonance frequency of the RFID transponders. These result from the temperature coefficients of the components used.


The typical resonance frequency of 13.56 MHz occurs at room temperature. The resonance frequency increases with lower temperatures. With higher temperatures, the resonance frequency drops.

The temperature coefficient of this change is approx. -3 kHz per Kelvin.

The specified temperature range for erase, read and write operations is -40° C to +85° C.
