3DC11X11 with cap SMD 3D Coil 11x11x3.6 mm (7.2 mH - 2.38 mH) with cap 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 sougth 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. Dimensions, electric diagram and pad layout All dimensions in mm
Pins coplanarity 0.15mm
