Patent ID: 7352270

Claim:
A magnetic assembly comprising: a printed circuit board; a core made from magnetically permeable material positioned on the printed circuit board; plated through holes formed in the printed circuit board, a first plated through hole on a first side of the core, a second plated through hole on a second side of the core and third plated through hole on the first side of the core; a winding lead having a first leg soldered in the first plated through hole and a second leg soldered in the second plated through hole, the winding lead being a discrete electrical conductor separate from the printed circuit board, the first leg extending through and beyond the printed circuit board opposite the core and the second leg extending through and beyond the printed circuit board opposite the core; a conductive trace formed in the printed circuit board, the conductive trace electrically connecting the second plated through hole and the third plated through hole; and a heat sink positioned on the printed circuit board opposite the core, the heat sink including a first recessed channel for receiving the first leg extending beyond the printed circuit board opposite the core, the heat sink including a second recessed channel for receiving the second leg extending beyond the printed circuit board opposite the core.
