1. What is a Choke Coil?

A choke coil is a part used in electrical circuits to allow DC current to flow through while blocking AC current from passing. Choke is an inductor used to block higher-frequency while passing direct current (DC) and lower-frequencies of 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.

YY Electronics provides a variety of choke coil, welcome to check it on our website.
