PREMO, leading manufacturer of LF RFID antennas, 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 18.52mHat a working frequency of 125 kHz and can be customized upon request with values from 0.34mH-18mH. These antennas offers up to 90mV/A/m sensitivity which give the best sensitivity in this transponder size(8.50mmx2.90mmx2.70mm).

Its NiZn ferrite core offers high surface resistivity (> 10Mohm/mm) and enables highly stable behavior (better than / +/- 3%) over a wide temperature range (-40 º C to 125 º C).

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 if mechanical strength. Its surface mount (SMT) allows an easy use in automated process.

The new TP0702UCAP, is particularly suitable for rugged applications such as TPMS (Tire Pressure Monitoring Systems) which requires an excellent performance under extreme conditions, according to AEC-Q200 and additional requirements as EU regulations. This antenna is also recommended for passive keyless entry (PKE) systems and immobilizers.
