A magnetic device includes: (1) a multi-layer circuit containing a plurality of windings disposed in layers thereof, the multi-layer circuit having inner lateral vias associated therewith, the inner lateral vias intersecting the layers of the multi-layer circuit, (2) a conductive substance disposed within the inner lateral vias and electrically coupling selected ones of the plurality of windings, (3) a magnetic core mounted proximate the plurality of windings and adapted to impart a desired magnetic property to the plurality of windings and (4) a compression-mounted electrical lead resiliently bearing against the conductive substance and electrically coupled to electrical conductors on the substantially planar substrate to conduct electricity therebetween, the plurality of windings and the magnetic core substantially free of a surrounding molding material to allow the magnetic device to assume a smaller overall device volume.
