RFID Transponder Inductors from The Premo Group

A transponder (short-for Transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation.

In aviation, aircraft have transponders to assist in identifying them on radar and on other aircraft's collision avoidance systems. 

In automotive applications, many modern automobiles have keys with transponders hidden inside the plastic head of the key. When the key is inserted into the ignition lock cylinder and turned, the car's computer sends a radio signal to the transponder. Unless the transponder replies with a valid code, the computer will not allow the engine to be started. Transponder keys have no battery; they are energized by the radio signal itself.

Other applications in the automotive market for transponders are immobilizers and TPMS (tire pressure monitoring systems).

RFID transponder inductors are used as antennas and provide the link between the interrogator and the transponder and operate at the nominal RFID frequency of 125KHz.

Premo offers the industry’s most comprehensive selection of RFID transponder inductors and antennas and their solutions have been chosen by many leading Tier 1 automotive system manufacturers in the United States and throughout Europe.
