Abstract

A ferrite core includes an end face portion, a pair of outer legs protruding from the end face portion, and a center leg protruding from the end face portion between the pair of outer legs. A width W1 close to one end portion of the center leg in a Y-axis direction perpendicular to a facing direction of the outer legs is smaller than a width W2 close to the other end portion. According to this configuration, a circuit component may be positioned close to the end portion. A transformer includes the ferrite core.

Description

technical field

[0001] The present invention relates to a ferrite core used in a wire-wound element suitable for various electronic devices and a bobbin corresponding to the ferrite core, and to a transformer including the ferrite core and the bobbin . Background technique

[0002] In the related art, there is known a ferrite core used in a wire-wound component installed in office machines and equipment, the ferrite core includes an end face, a pair of outer columns protruding from both sides of the end face , and a central column protruding from the end face between the outer columns. A center post of a conventional ferrite core has a circular, polygonal, elliptical or oval cross section, and an inductor such as a choke coil or a transformer is constituted by inserting the center post into a bobbin of a bobbin wound with a wire.

[0003] Such as Figure 21 As shown, a ferrite core 40 for a transformer is disclosed in Patent Documents 1 and 2, which has an elliptical or ov...
