低频接收3D天线---12.6x12.6x3.25
SMD 3D Coil 12.6x12.6x3.25 mm
Features
Dimensions
Keyless entry systems is a typical application for this coil,
theisotropy is often sought in RF
antenna. In transponder applications, this feature has beenachieved
by the combination of 3
single coils oriented in the 3 space axis with the aim of
coveringthe maximum space
orientation.
This small size 3D coil offers the possibility of assembly insingle
component 3 coils with full
functionality, thus reducing cost, saving PCB space and
increasingthe circuit reliability.
Small solution of 3D coil designed to achieve a very
good electrical performance in the smallest dimensions.
Applications:
- Automotive.
- Passive keyless entry and Keyless Go Systems.
- RTPMS with wake up functions.
- Industrial logistics and control.
- Access control.
- Tracking devices.
