3DC11LP
SMD 3D Coil 13x11.6x3.15 mm MAX (2.38 mH – 7.2 mH) Low pro le
3-Axes Transponder Inductor (3DCoils)
Characteristics
- Offers 3 coils, oriented in the 3 space axes, assembled in a single component with
full functionality.
- Suitable for automotive applications (Keyless Entry Systems, RTPMS), etc.
- Very good electrical performance in the smallest dimensions.
- High stability in temperature (-40ºC to +85ºC).
- High sensitivity values.
- The inductivity in each axis can be customized to achieve customer requirements.
- Designs at lower frequencies, 20 kHz or 40 kHz, show
a very good electrical performance as well.
