Common Mode Choke Coil Toroidal Power Inductor with base
Description:
Common-mode inductance is a common-mode interference suppression device with ferrite as the core. It consists of two coils of the same size and number of turns wound symmetrically on the same ferrite annular core to form a four-terminal device, which can suppress the large inductance of common-mode signal, but has little effect on the leakage inductance of differential-mode signal. The principle is that the flux in the magnetic ring superimposes each other when the current flows through the common mode, which has a considerable inductance and inhibits the common-mode current. When the two coils flow through the differential mode current, the flux in the magnetic ring cancels each other and there is almost no inductance, so the differential mode current can pass through without attenuation. Therefore, common-mode inductors can effectively suppress common-mode interference signals in balanced circuits without affecting the normal transmission of differential-mode signals.
