A surface mount power inductor component for a circuit board including multi-phase power supply circuitry includes a single piece, integrally fabricated magnetic core piece formed with vertically extending interior passageways provided with vertically elongated pre-formed conductive windings that are not magnetically coupled to reduce the footprint of the inductor component while increasing its power capacity. A distributed gap material is also provided in the vertical passageways with the conductive windings that respectively connect to each phase of electrical power.

Integrated multi-phase power inductor with non-coupled windings and methods of manufacture

A surface mount, power inductor component assembly includes only two different shapes of modular core pieces and a set of windings having the same shape that can be assembled and arranged to have any desired number of non-magnetically coupled windings to accommodate electrical power systems having different numbers of phases of electrical power. The core pieces and windings are vertically elongated to reduce the component footprint on a circuit board yet provide higher power, higher current capability.
