Abstract

PURPOSE: To block high frequency while lessening the drift capacity ensuring flat characteristics in a wider band by inserting a conductor through a small through hole made on a ferromagnetic material in an element for preventing current of high frequency such as VHF and UHF.
CONSTITUTION: A circular ferromagnetic material 1 is made of ferrite material or the like large in the loss coefficient with respect to frequency used and a plurality of small through holes 2 are made parallel to the axis of the material. A conductor 3 is inserted folded into the small through holes and connected to terminals 4 and 5. The portion of the conductor exposed from material 1 is minimized while maximized in the electromagnetic connection with the ferromagnetic material between terminals 4 and 5 with respect to high frequency. In this manner, a high impedance is formed even in the short conductor thereby reducing the drift capacity and ultimately assuring effective blocking of high frequency.
