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 beenachievedby the combination of 3
single coils oriented in the 3 space axis with the aim ofcoveringthe maximum space
orientation.
this small size 3d coil offers the possibility of assembly insinglecomponent 3 coils with full
functionality, thus reducing cost, saving pcb space andincreasingthe 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.
