Title:
NOISE FILTER
Document Type and Number:
Japanese Patent JPS59147518
Kind Code:
A
Abstract:

PURPOSE: To suppress sufficiently a pulsive component by interlinking a coil in common use with a capacitor where a through-hole is formed at the center with a magnetic core forming a closed magnetic path while being fitted to the through-hole so as to constitute a filter for the use of a smoothing circuit.

CONSTITUTION: Lead wires 5, 6 are connected to both ends of a strip conductor made of two conductor foils 3 or the like and the coil in common use with the capacitor element 10 is formed by clipping the two strip conductors having an insulation sheet 7 in between. The through-hole 8 is formed to the center of the element 10, which is inserted to a magnetic core forming a closed magnetic path possible for assembling as a pot type core 11 or an EI type core 12 or the like so as to form noise filter elements 13, 14. Then, the manufacture of the element of the noise filter is made easy, the noise filter is used for the smoothing circuit of a power supply circuit so as to suppress sufficiently the pulsive current.
