Abstract:
A winding body for a low profile magnetic component, the winding body having an upper surface, a lower surface, an outer sidewall, and an inner sidewall defining a central aperture extending from said upper surface to said lower surface;the body being constituted by a stack of substantially planar layers, each layer having a planar winding pattern formed by a continuous track of electrically conductive material, each said track having at least two turns and ends terminating at respective sidewalls of the body, and an electrically insulating binding material between the turns of each track; andplated metal interconnections selectively formed on the sidewalls of the body, said interconnections on the inner and outer sidewalls serving to directly interconnect the winding pattern on each respective layer to a winding pattern on at least one other of said layers as well as to provide for external connections to the winding patterns of the layers connected thereto.
