Through-Hole Common Mode Choke

choke coil 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.

We also do ferrite cores,bobbins,iron power cores,amorphous cores,sendust cores,etc.,accessories.The products are exported to more than 40 countries and regions.

Our operating policy is "Quality comes first, customer foremost".We know customer's satisfaction is the only benchmark to verify our works.Engaging,learning and mastering advanced technology,Fullstar excellent team provide high quality products,quick delivery,strong technical support&best service and would help our customers achieve the maximum value.
