Features

This TP0702 Series of Surface Mountable ferrite wound

inductor is a stronger solution in very small dimensions

performing very good electrical properties, a very good

solution for RTPMS, Keyless Go and Keyless entry

systems.

Characteristics:

- Size: 7.7 x 3 x 2.2 mm.

- Very good mechanical performance.

- High sensitivity in the smallest volume.

- Very stable electrical properties in full operational

temperature range (-40

J +125 ºC).

- Good performance in thermal shock.

- Big metallised pad area Pb free.

- Good cost/performance ratio.

- Due to its small dimensions, it’s a suitable design for

other applications working at lower frequencies.

- This component is also functional to 20kHz and

134kHz.
