するチョークコイル。In a choke coil formed by winding a magnetic core, a groove with a V-shaped cross section extending in a direction transverse to the magnetic path is formed in a part of the surface of the magnetic core, thereby increasing the inductance value by superimposing a direct current on the winding. A choke coil that is characterized by being made to change.
