Abstract
A low profile magnetic component such as an inductor or transformer includes a core and a planar magnetic winding body having a dense, rigid structure composed of a stack of individual winding patterns separated by insulating layers, and a binder/filler material. The input and output termini of the individual winding patterns are revealed in a side face of the winding body, where they are interconnected with a plated metallization. Such structures may be mounted onto a PC board, and are useful, for example, in electronic ballasts for the lighting industry.
