Abstract
An inductive element includes a magnetic core, a flat coil wound on a middle column of the magnetic core, and a magnetic plastic package layer covering the magnetic core and the flat coil. Two electrodes connected to two pigtails of the flat coil are exposed outside of the magnetic plastic package layer. The flat coil is configured to enable a width direction of a flat wire of the flat coil to be perpendicular to an axial direction of the middle column of the magnetic core, and the flat wire is stacked layer by layer in the axial direction of the middle column. A manufacturing method for the inductive element is also disclosed herein. By using the wounding method of the flat coil of the inductive element, a height of a product may be reduced while obtaining a same DCR, so that the product is thinner.
