1. Product Introduction of CDRRID Inductance
Production details: CDRRID inductance Power Supply Standard compliance inductance is an improvement on the basic functions of I-shaped inductors. In order to protect the wires, loops and coils from the external magnetic field, and to weaken the interference effect of the electromagnetic field generated by the circuit on other components, magnetic materials are used. An inductance mode for shielding, whose main function is like reducing the inductance's interference to the outside world.
