COMPOSITE COIL COMPONENT AND ELECTRONIC CIRCUIT UNIT

WIPO Patent Application WO/2023/276658

A1

Provided are a composite coil component and an electronic circuit unit, wherein a DC power-supplying coil is made into a single coil, and unnecessary radiation caused by the DC power-supplying coil is suppressed. The composite coil component comprises: a magnetic support body; a first electrode pair, a second electrode pair, and a third electrode which are provided to the support body; two first coils serving as first common mode choke coils; two second coils serving as second common mode choke coils; and a third coil wound around the support body. The two first coils each have one end, the ends being respectively connected to electrodes of the first electrode pair, and the two second coils each have one end, the ends being respectively connected to electrodes of the second electrode pair. One end of the third coil is connected to a third electrode. The other end of one coil of the two first coils, the other end of one coil of the two second coils, and the other end of the third coil are electrically connected. The other end of the other coil of the two first coils, and the other end of the other coil of the two second coils are electrically connected.
