ズフイルタ。 A filter circuit is constructed by fixing a chiyoke coil 22, which has a ring-shaped core covered with an insulating case 23 and windings 24, 24, on a base plate 21, and connecting capacitors 26, 27, 27 to the chiyoke coil 22. In a power supply noise filter in which the chiyoke coil 22 and capacitors 26, 27, 27 are housed in a metal case 25, a pair of flat protrusions 29, 29 are attached to the base at intervals corresponding to the outer diameter of the chiyoke coil 22. The coil 22 is placed upright on the plane of the plate 21, and the coil 22 is fitted between the protrusions 29, 29, and the coil 22 is inserted between the protrusions 29, 29 from both sides.
A noise filter for a power supply, characterized in that it is fixed by being sandwiched between 9.
