Title:
INDUCTOR COMPONENT
Document Type and Number:
WIPO Patent Application WO/2022/181180
Kind Code:
A1
Abstract:
A plurality of thin magnetic strips (40A to 40F) are layered in a direction orthogonal to a main surface of the thin magnetic strips (40A to 40F). In the cross section orthogonal to the central axis of an inductor wiring, the axis along the main surface is a first axis (X), and the axis orthogonal to the main surface in the cross section is a second axis (Z). An element assembly has the plurality of thin magnetic strips (40A to 40F) and a plurality of non-magnetic layers (50A to 50E). The plurality of thin magnetic strips (40A to 40F) are layered along the second axis (Z). Each of the non-magnetic layers (50A to 50E) is positioned between thin magnetic strips (40A to 40F) adjacent along the second axis (Z). The average value of the dimension of the thin magnetic strips (40A to 40F) in the direction along the second axis (Z) is the thin magnetic strip thickness, and the average value of the dimension of the non-magnetic layers (50A to 50E) in the direction along the second axis (Z) is the non-magnetic layer thickness. In this case, the percentage of the non-magnetic layer thickness with respect to the thin magnetic strip thickness is greater than 3%.
