Inductors: Miniaturized transponder coil with high sensitivity for tire pressure monitoring systems
- 30 percent smaller footprint than its predecessor
- High sensitivity of nearly 25 mV/μT despite miniaturization
- Qualified to AEC-Q200
Mar 13, 2018
TDK Corporation presents the miniaturized TPLC553030-592H automotive transponder coil for tire pressure monitoring systems (TPMS) that operate at a center frequency of 125 kHz.
With its dimensions of just 5.5 mm x 3.0 mm x 3.0 mm, the new component features a footprint that is 30 percent smaller than its predecessor. Thanks to its optimized core geometry and material, the miniaturized component achieves a high sensitivity of nearly 25 mV/μT, which allows TPMS initialization at the same distance as its 8-mm predecessor.
The new transponder coil 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.
