INDUCTOR COMPONENT

Document Type and Number:

WIPO Patent Application WO/2022/181179

Kind Code:

A1

Abstract:

A plurality of thin magnetic strips (40A to 40F) are stacked in a direction orthogonal to the principal surfaces of the thin magnetic strips (40A to 40F). In a cross section orthogonal to the center axis of an inductor wire, an axis extending along the principal surfaces is denoted as a first axis (X) and an axis orthogonal to the principal surfaces in the cross section is denoted as a second axis (Z). An element assembly includes 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 stacked along the second axis (Z). The non-magnetic layers (50A to 50E) are each located between the thin magnetic strips (40A to 40F) adjacent to each other along the second axis (Z). The mean value of the dimensions of the thin magnetic strips (40A to 40F) along the second axis (Z) is referred to as a magnetic layer thickness, and the mean value of the dimensions of the non-magnetic layers (50A to 50E) along the second axis (Z) is referred to as a non-magnetic layer thickness. At this point, the percentage of the non-magnetic layer thickness with respect to the magnetic layer thickness is 15% or less.
