Low profile high current coupled winding electromagnetic component

A low profile surface mount electromagnetic component for multi-phase electrical power circuitry implemented on a circuit board, the electromagnetic component comprising:

• a magnetic core structure including a top wall, a bottom wall, a first pair of opposed side walls interconnecting the top and bottom wall, and a second pair of opposed side walls interconnecting the first pair of side walls and the top and bottom walls;
• and
• at least one dual-winding arrangement in the magnetic core structure and configured to be surface mounted to the multi-phase electrical power circuitry on the circuit board with the bottom wall adjacent a plane of the circuit board, wherein the at least one dual-winding arrangement comprises:
• a first winding fabricated from an elongated conductor having a first thickness, the first winding including a first elongated planar main winding section extending linearly in a plane parallel to and spaced from the bottom wall and extending entirely across the magnetic core structure;
• a second winding fabricated from a conductor having a second thickness less than the first thickness, the second winding including a second elongated planar main winding section extending linearly in a plane parallel to and spaced from the plane of the first elongated planar main winding section of the first winding and extending entirely across the magnetic core structure;
• wherein one of the first elongated planar main winding section and the second elongated planar main winding section overlies the other in the magnetic core structure and wherein the first and second windings are magnetically coupled to one another;
• and
• a separator element separating the first elongated planar main winding section and the second elongated planar main winding section inside the magnetic core structure.
