3DC11LPCAP
SMD CAP 3D Coil 13x12.8x3.7 mm (2.38 mH - 7.2 mH) Low Pro le
Characteristics
- Evolution of the 3DC11LP series.
- The cap, made of high quality plastic material,
improves the mechanical protection to the coil.
- Keyless Entry Systems is a typical application for
this coil.
- Very good electrical performance.
- High stability in temperature (-40ºC to +85ºC).
- High sensitivity values.
- The inductance in each axis can be customized to
ssachieve
customer requirements.
- Designs at lower frequencies, 20 kHz or 40 kHz,
show a very good electrical performance as well.
