Title:
MAGNETIC CORE, INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2021/059829
Kind Code:
A1
Abstract:
The present invention makes it so that fluctuation in the inductance of an inductor is suppressed when the two magnetic cores that are used in the inductor have shifted. According to the present invention, a first core has a yoke and a first leg, a second leg, and a third leg that are connected to the yoke. The second leg, the first leg, and the third leg are aligned in that order in a first direction and extend in a second direction. A second core has a first surface, a second surface, and a third surface that are respectively opposite the first leg, the second leg, and the third leg in the second direction. The first surface is recessed further from the first core in the second direction than the second surface and the third surface, forming a recessed part in the second core. A first distance that separates the first surface and the first leg is greater than a second distance that separates the second surface and the second leg and a third distance that separates the third surface and the third leg. In the first direction, the first surface is longer than the first leg, the second surface is longer than the second leg, and the third surface is longer than the third leg.
