High-Q transponder coils target TMPS applications

November 07, 2013 // By Julien Happich
Premo expands its TP0702CAP family of transponder coils with an improved version with higher Q and sensitivity specially designed for Tire Pressure Monitoring Systems (TPMS) applications.

The TP0702UCAP series is offered in five standard values, 2.38mH, 4.91mH, 7.2mH, 9mH and 18.52mH at a working frequency of 125 kHz and can be customized upon request with values from 0.34mH to 18mH. Sensitivity is up to 90mV/A/m in a transponder measuring 8.50x2.90x2.70mm. The NiZn ferrite core offers high surface resistivity (greater than 10Mohm/mm) and supports a highly stable behaviour over a wide temperature range of -40 to 125ºC). This rugged antenna provides an upper and lateral side protection with co-polyamide polyhexamethylene polymer walls, gamma radiated with high thermal stability and mechanical resistance (exceeds 150Mpa in mechanical strength).
