Product Name：Common mode coils
When the common-mode current flowing through the magnetic flux in the superposition, so as to have a considerable inductance, play an inhibitory effect on the common mode current, and when the two differential-mode current flowing through the coil, the magnetic flux in the mutual offset, almost no inductance, so the differential-mode current can pass without attenuation. Therefore, the common mode inductance in a balanced line can effectively suppress common mode interference signal, but had no effect on the transmission line is normal differential mode signal.

Common mode inductance characteristics:
Common mode inductor is also called common mode choke coil for a ferrite core common mode interference suppression device, which consists of two identical size, the same number of turns of the coils wound symmetrically in the same toroidal magnetic ferrite core, forming a four-terminal device, to common mode signal exhibits large inductance inhibited, and for differential mode signal showing a small leakage inductance almost no effect. Often used in higher initial permeability of the ferrite core to produce, mainly produced by the ring core, but also according to customer requirements with other types (UU, ET, EE, etc.).
