High Power Toroidal Common Mode Inductors

Common mode inductor, sometimes called common mode choke coil, is one of the common EMC electronic devices used to filter out common mode electromagnetic interference.

Basic principle: When passing through the common mode current, the magnetic flux in the magnetic core accumulates with each other, thus having a very large inductor quantity, which has an inhibitory effect on the common mode current. However, when two Coils pass through the differential mode current, the magnetic flux in the magnetic core counteracts each other, and there is basically no inductor quantity, so the differential mode current can be based on without attenuation coefficient. Therefore, the common mode inductor can reasonably suppress the common mode electromagnetic interference in the equalization route, but has no harm to all the Jammu data signals transmitted normally in the route.
