Title:
INDUCTANCE ELEMENT AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/178737
Kind Code:
A1
Abstract:
An inductance element and manufacturing method therefor. The inductance element comprises magnetic cores (100, 200), flat coils (110, 210) wound on center pillars (105, 203) of the magnetic cores, and magnetic plastic package layers (108, 205) covering the magnetic cores and the flat coils. Two electrodes connected to two leading-out ends (106, 107, 201, 202) of the flat coils are exposed out of the magnetic plastic package layers, wherein the flat coil is configured in such a manner that a width direction of a flat wire which forms the flat coil is perpendicular to the axial direction of the center pillar of the magnetic core, and the flat wire is laminated layer by layer in the axial direction of the center pillar. According to a winding mode of the flat coil of the inductance element, the height of a product can be reduced while the same DCR is obtained, so that the product is thinner.
