TP0702
7.7x3x2.2 mm (2.38 mH - 10.8 mH)
SMD Hard Ferrite Mechanically Improved Transponder Inductor
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.
