CHOKE COIL

摘要

PROBLEM TO BE SOLVED: To provide a chock coil capable of easily changing inductance for a constant input current. SOLUTION: There are provided a drum-like core 13 having a collar 12 on both ends of an axial core 11; a winding 14 wound on the surface of the outer periphery of the drum-like core 13; an electromagnet 15 for generating a magnetic field in the axial core 11 of the drum-like core 13; a terminal stand 17 mounting the drum-like core 13 upward; and a terminal 18 which is embedded in the terminal stand 17 and electrically connected to the winding 14. The electromagnet 15 is formed by winding an electromagnet winding 16 around a closed magnetic path magnetic core 19 with one collar 12 of the drum-like core 13 being one magnetic leg.
