Abstract
An inductive component comprises a hollow coil wound by Litz wire, a magnetic plastic packaging layer covering the coil, and a first electrode and a second electrode of the coil. The first electrode and the second electrode are exposed outside the magnetic plastic packaging layer. A manufacturing method for the inductive component comprises: winding a hollow coil by using Litz wire; connecting two leading-out terminals of the coil to portions of a leadframe to be formed into two electrodes; manufacturing a formed magnetic plastic packaging layer on the periphery of the coil; curing the magnetic plastic packaging layer through heat treatment; and carrying out leadframe cutting on the cured semi-finished product to form the two electrodes exposed outside the magnetic plastic packaging layer, and bending the two electrodes to flatly extend to the surface of the magnetic plastic packaging layer.
