US Patent 10325715 Low profile electromagnetic component

A low profile electromagnetic component assembly for a circuit board such as a power inductor includes a first shaped magnetic core piece comprising a bottom surface for seating upon the circuit board, a top surface opposing the bottom surface, and a groove defined on the top surface. A conductive coil winding includes first and second terminal sections and a center main winding section extending between the first and second terminal sections. The center main winding section comprises an elongated strip of conductor having a thickness oriented extend to perpendicular to a plane of the circuit board. The terminal sections define a different cross sectional area of conductor than in the center main winding section.
