TDK's TPLC553030 series automotive transponder coil was designed for use in tire pressure monitoring systems (TPMS) that operate at a center frequency of 125 kHz. With miniaturized dimensions of just 5.5 mm x 3.0 mm x 3.0 mm, this new component features a footprint that is 30% smaller than its predecessor. Thanks to the optimized core geometry and material, a high sensitivity of nearly 25 mV/µT is achieved, allowing TPMS initialization at the same distance as its 8 mm predecessor. High reliability is ensured for automotive applications due to the use of highly heat resistant wire and the welding wire connection. The TPLC553030 has an inductance of 5.89 mH with a minimum Q value of 35 and a maximum DC resistance of 70 Ω. The AEC-Q200 qualified and RoHS-compatible component features a wide temperature range from -40°C to +125°C.
