Abstract: 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.

Abstract: A surface mount power inductor includes a preformed conductive winding clip and first and second-shaped core pieces. The core pieces may be configured to reduce unbalanced force experienced in the power inductor in certain types of power management circuitry. Reduction in the unbalanced force reduces vibration of the power inductor in use, and in turn reduces acoustic noise as the power inductor operates.
