Abstract
An electromagnetic component such as a power inductor includes first and second magnetic core pieces and a preformed coil winding therebetween. The preformed coil winding includes a top winding section and a pair of coplanar winding legs defining a U-shaped winding section therewith. The pair of winding legs are oriented perpendicular to a circuit board in use. First and second surface mount terminals respectively extend perpendicular to the pair of winding legs in opposing directions to each other, such that each of them extends only on one of the first and second magnetic core pieces but not the other.
Claims20
An electromagnetic component assembly for a circuit board, the component assembly comprising:
- a magnetic core assembled from a first magnetic core piece and a second magnetic core piece, wherein each of the first magnetic core piece and the second magnetic core piece each include a top side and a bottom side, wherein the top side is elevated from the circuit board and the bottom side is proximate the circuit board in use, and wherein the first magnetic core piece and the second magnetic core piece are arranged side-by-side;
- and
- a first preformed conductive coil winding received by at least one of the first magnetic core piece and the second magnetic core piece, wherein the first preformed conductive coil winding includes:
- a top winding section extending to the top side of at least one of the first magnetic core piece and the second magnetic core piece;
- a pair of winding legs extending from opposing ends of the top winding section and defining a U-shaped winding section therewith, wherein the pair of winding legs extend coplanar to one another and are oriented perpendicular to the circuit board in use, the pair of winding legs further being located in between the first magnetic core piece and the second magnetic core piece;
- and
- first and second surface mount terminals respectively extending perpendicular from the pair of winding legs opposite the top winding section, wherein the first surface mount terminal extends in a first direction and solely on the bottom side of the first magnetic core piece, and wherein the second surface mount terminal extends in a second direction solely on the bottom side of the second magnetic core piece.
