Abstract

PURPOSE:To make even a normal mode noise on a low frequency region removable effectively without an exclusive choke coil and a capacitor of large capacity, by forming a structure with no decrease in leakage inductance even if a balun choke is located in a metal case made of a magnetic material. CONSTITUTION:A balun choke 1 is provided with a rectangular magnetic core of a closed magnetic path which is divided into two regions 2a, 2b on alternate long and short dashes line positions in the direction of its long side, and each one of windings 3, 4 is wound on three sides of each region in the direction that two species of magnetic flux generated by their forward and backward currents are canceled to each other. This balun choke 1 is located in a metal case made of a magnetic material. Since each one of two species of the magnetic flux generated by the windings 3, 4 travels through the three sides of the magnetic core 2, two species of leakage flux 5 and 6 pass to short long sides of the magnetic core 2, as shown in a figure, inside loops of the magnetic core 2.
