Abstract
A wireless transponder unit having a maximum operating temperature and being structured to be disposed on an electrical joint includes: an integrated circuit configured to store identification information; and a resonant circuit electrically connected to the integrated circuit, the resonant circuit having a damping factor. The resonant circuit includes a capacitor, an antenna, and a resistor having a resistance and a positive thermal coefficient. A change in temperature of the wireless transponder unit causes a change in the resistance of the resistor and the damping factor of the resonant circuit. The maximum operating temperature of the wireless transponder unit is based on the damping factor of the resonant circuit.
