Title:
FERRITE MAGNETIC CORE, AND COIL COMPONENT AND ELECTRONIC COMPONENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/163930
Kind Code:
A1
Abstract:
The present invention provides a ferrite magnetic core provided with: a columnar middle leg part; a first outer leg part and a second outer leg part which, in a direction perpendicular to the axial direction of the middle leg part, are disposed on both sides of the middle leg part to be spaced apart from each other; a first connection part which connects the middle leg part and the first outer leg part at base parts thereof; and a second connection part which connects the middle leg part and the second outer leg part at base parts thereof, wherein when the ferrite magnetic core is viewed from above in the z-axis direction while taking the axial direction of the middle leg part as the z-axis direction, the direction in which the first outer leg part and the second outer leg part face each other as the y-axis direction, and the direction perpendicular to the y-axis and the z-axis as the x-axis direction, and having the base parts of each of the leg parts facing downward, the width w1 of the first outer leg part in the x-axis direction is larger than the width w2 of the second outer leg part in the x-axis direction, and the width d1 of the first outer leg, which is along a y-axis direction straight line passing through the center of the middle leg part, is smaller than the width d2, which is along the y-axis direction straight line passing through the center of the middle leg part.
