Common-mode inductors from China manufacturer are also called common mode choke coils, which are often used in computer switching power supplies to filter common mode electromagnetic interference signals. In the design of the board, the Common-mode inductors from China manufacturer also plays the role of EMI filtering, which is used to suppress the electromagnetic wave generated by the high-speed signal line and radiate to the outside.
The principle of Common-mode inductors from China manufacturer：
The filter circuit of the Common-mode inductors from China manufacturer, La and Lb are the common mode inductor coil. The two coils are wound on the same core with the same number of turns and phases (winding reversed). In this way, when the normal current in the circuit flows through the Common-mode inductors from China manufacturer, the currents generate opposite magnetic fields in the inductive coils wound in the same phase and cancel each other out. At this time, the normal signal current is mainly affected by the coil resistance; When the current flows through the coil, due to the same direction of the Common-mode inductors from China manufacturer, a magnetic field in the same direction will be generated in the coil to increase the inductive reactance of the coil, so that the coil exhibits high impedance and produces a strong damping effect, thereby attenuating the common mode. mode current to achieve the purpose of filtering.
