| SMD 3D Coil 12.6x12.6x2.9 mm | ||||||||||
| Features | ||||||||||
| 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. | ||||||||||
| Keyless entry systems is a typical application for this coil, the isotropy is often sought in RF antenna. In transponder applications, this feature has been achieved by the combination of 3 single coils oriented in the 3 space axis with the aim of covering the maximum space orientation. This small size 3D coil offers the possibility of assembly in single component 3 coils with full functionality, thus reducing cost, saving PCB space and increasing the circuit reliability. | ||||||||||
