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.
