Choke Coil Inductor

Common mode choke, abbreviated as CMC, also known as common mode choke, is commonly used in switching power supply to filter common mode EMI signal. In the circuit design, the common mode inductor also plays the role of EMI filtering. Common mode inductance is used to make differential mode signal (required signal) pass through, while common mode signal (noise) cannot pass through. It can be used in electronic products, personal computers, switching power supply and so on.

Choke coil, also known as inductor coil, reactance coil or impedance coil, is an electronic component that plays an important role in controlling the magnitude and phase of current in an AC circuit. It can isolate high frequency currents, generate inertial potentials, and limit the passage of current, thus realizing the control of current in the circuit.
