Description

T-DW7029A Common Mode Chokes Manufacture Customized

A 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,

Toroidal Inductor coils Feautures:
(1) Vertical structure,small,lightweight design.
(2) Inductive interference rare.
(3) small size high power inductors.
(4) excellent Q frequency characteristice and small distributed capacity contributes to high self-resonant frequency.
(5) High dielectric strength and insulation resistance

Applications:

(1) Video cameras.
(2) Portable VCRs.
(3) Audio equipments.
(4) TV tunners.
(5) Switching power supplies.
(6) Other circuits of consideration aganist radiation..
