As the core component for suppressing electromagnetic interference, the inductance deviation of common mode filter inductors directly affects the stability of the filtering effect.
In high-frequency applications, ferrite cores have become the mainstream choice for suppressing eddy current losses due to their high resistivity.
Reverse winding reduces the interference of the differential mode magnetic field on the magnetic core, thereby reducing energy loss at high frequencies and delaying core heating and performance degradation.
After winding, the inductor needs to undergo high-temperature aging treatment to eliminate residual stress between the windings.
Magnetic ring filter inductors—typically composed of a toroidal core made of ferrite material and a through-wire—effectively suppress the propagation of high-frequency noise without the need for an external power supply or complex circuitry, thanks to the
In the context of modern electronic devices increasingly pursuing thinness, efficiency, and intelligence, switching power supplies have become the "heart" of almost all electrical products.
