Abstract
An integrated multi-phase inductor component assembly includes a single piece core or a multi-piece magnetic core that may be easily assembled with multiple coils arranged in a mirror-image relationship in the magnetic core. The coils include vertically extending, planar main winding sections extending in spaced apart but parallel vertical planes and horizontal sections extending in coplanar relationship on top and bottom sides of the magnetic core for surface mounting to a circuit board or through hole mounting to another circuit board or another component in power supply circuitry for an electronic device.
Claims17
An inductor component assembly for a circuit board, the inductor component assembly comprising:
- a magnetic core structure having a top side and a bottom side opposing the top side and at least one coil slot extending from the bottom side to the top side;
- and
- at least one conductive coil comprising a planar surface mount terminal section extending on the bottom side for connection to the circuit board, a planar terminal section on the top side, a terminal tab extending perpendicular to the planar terminal section, and a planar main winding section extending perpendicularly to the planar surface mount terminal section;
- wherein the at least one conductive coil is received in the magnetic core structure and the planar main winding section extends through the at least one coil slot.
