Title:
HIGH FREQUENCY CHOKE COIL
Document Type and Number:
Japanese Patent JPH0529148
Kind Code:
A
Abstract:
PURPOSE: To provide a small size and easily producible high frequency choke coil.
CONSTITUTION: In the case of a choke A, a belt-shaped magnetic plate 2 corresponds to a ferrite beads of a conventional choke and a single lead wire 3 formed by meandering a conductor foil by a printed wiring technology corresponds to a coil of the conventional choke. A coil 3 providing a large high frequency loss can be formed by winding the magnetic plate 2 as the substrate. As a result, the winding process to the ferrite beads which is very troublesome work can be eliminated and a small size choke 1 can be obtained.
