TP0702U

SMD Transponder Coil

Characteristics

- Size: 8x2.2x2.5mm.

- Very good mechanical performance.

- High sensitivity in the smallest volume.

- Very stable electrical properties

in full operational temperature

range (-40, +125ºC).

- Good performance in thermal shock.

- Big metallised pad area Pb free.

- Good cost/performance ratio.

Applications

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

design for other applications working at lower

frequencies.

- Terminals: Ag-Ni-Sn100.

- Wire: H, 125ºC, Solderable.

- Max. Operating Temperature 150ºC.
