モンモードチヨークコイル。 Magnetic flux generated by a signal current flowing between two windings in the winding core of a winding frame that is integrally formed with a cylindrical winding core made of an insulating material and flanges provided at the center and both ends of the winding core. A common mode chip is formed by winding the two U-shaped magnetic cores in directions that cancel each other out, one of the magnetic legs of two U-shaped magnetic cores is inserted into the winding core, and the two U-shaped magnetic cores butt against each other to form a closed magnetic circuit. In the yoke coil, grooves are provided on both sides of the center flange of the winding core and on the upper and lower ends of the inner surface of the flange at both ends, and the legs use four U-shaped magnetic plates having wide edges,
The common mode chip is characterized in that the edges of the legs are inserted into the grooves provided in each of the flanges, with the magnetic plates facing each other, and the two windings are covered with the magnetic plates. yoke coil.
