TDK has launched a miniaturized automotive transponder coil with high sensitivity for tire pressure monitoring systems (TPMS) that operate at a center frequency of 125 kHz.
Key benefits include a footprint of just 5.5 mm x 3.0 mm x 3.0 mm that is 30 percent smaller footprint than its predecessor, high sensitivity of nearly 25 mV/μT despite miniaturization, and AEC-Q200 certification.
A high sensitivity of nearly 25 mV/μT allows TPMS initialization at the same distance as its 8-mm predecessor, says TDK.
Other specs include 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.
