Title:
MAGNETIC CORE AND INDUCTOR
Document Type and Number:
Japanese Patent JP2021057380
Kind Code:
A
Abstract:
To suppress variation in inductance of an inductor when two magnetic cores used in the inductor are displaced from each other.SOLUTION: A first core has: a yoke; and a first leg, a second leg, and a third leg which are coupled to the yoke. The second leg, the first leg, and the third leg are aligned along a first direction in this order, and they each extend in a second direction. A second core has a first surface, a second surface, and a third surface which respectively face the first leg, the second leg, and the third leg in the second direction. The second core is configured such that the first surface is shaped as a recess which retracts farther than either the second surface or the third surface from the first core along the second direction. A first distance separating the first surface from the first leg is greater than either a second distance separating the second surface from the second leg or a third distance separating the third surface from 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.SELECTED DRAWING: Figure 3
