Common Mode Choke

    详细说明

        In electronics, a choke coil is an inductor used to block higher-frequency while passing lower-frequency of direct current (DC) or alternating current (AC) in an electrical circuit, A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped "bead" of ferrite material strung on a wire. The choke's impedance increases with frequency. Its low electrical resistance passes both AC and DC with little power loss, but its reactance limits the amount of AC passed.  WIKIPEDIA
