How to identify the Common mode choke core and differential mode choke core it is very simple

2019-04-04 10:13:37

Common mode choke core and differential mode inductor core are one of the effective components for anti-electromagnetic interference. They are widely used in various filters, switching power supplies, etc., but common mode inductors are used to suppress common mode interference, and poor. The mode inductor is used to suppress differential mode interference. Both the Common mode choke core and the differential mode inductor core are important filter inductors.

 

Although the two inductors are filter inductors, the effect is different, which determines the appearance and the winding method. For the Common mode choke core, it is wound on the same core and the coil diameter of the two windings. Same as the number of turns, but in the opposite direction of the winding, one set of coils has two pins, so the common mode inductor has 4 pins; and the differential mode inductor core is wound around a core and has only one coil. Therefore, it has only 2 pins, so the common mode inductor core and the differential mode inductor core can be distinguished from the number of pins.http://www.wenergytech.net/
