Ferrite core inductor toroidal common mode choke coil toroidal inductor for switch power supply
Common mode Choke, also known as Common mode Choke, is commonly used to filter Common mode EMI signals in switching power supplies of computers.In board card design, common-mode inductor also plays the role of EMI filter, which is used to suppress the electromagnetic wave emitted by high-speed signal line.
