Differential Mode Choke
Differential mode inductors, also known as differential mode chokes, are electronic components specially designed to suppress differential mode electromagnetic interference (DMI). Their structure usually includes a winding wound around a core made of ferrite or other magnetic materials. The main function of differential mode inductors is to filter out electromagnetic interference caused by differential mode current on power lines or signal lines, thereby improving circuit stability and signal quality. It is widely used in power supplies, communication equipment, computers and peripheral equipment, etc., and plays an important role in suppressing high-frequency differential mode noise. Differential mode inductors have the characteristics of small size, light weight, easy installation and integration, and are indispensable electromagnetic interference suppression components in electronic equipment.
