CONNECTOR WITH BUILT-IN FILTER

WIPO Patent Application WO/2013/014957

A1

[Problem] To provide a connector with a built-in common mode noise-robust filter that is smaller than a conventional connector that utilizes a common mode choke coil. [Solution] The connector has a common mode filter that is provided between multiple first external terminals for connecting to a counterpart connector and second external terminals for connecting to other device. The common mode filter has: a magnetic body-containing magnetic layer that is formed as an outer layer on each side; and multiple coil layers and a ground layer as inner layers. At least one of the magnetic layers is provided with: first extraction electrodes; third extraction electrodes that are connected to the first extraction electrodes; second extraction electrodes; and fourth extraction electrodes that are connected to the second extraction electrodes. At least the other of the magnetic layers is provided with a first ground electrode and a second ground electrode that are respectively connected to a ground conductor. The third extraction electrodes, the fourth extraction electrodes, and the second ground electrode are connected to the second external terminals.
