An electrical assembly includes a substrate, a bridge magnetic device disposed on an outer surface of the substrate, and at least one electrical component. The bridge magnetic device includes (1) a magnetic core disposed over and offset from a first portion of the outer surface of the substrate, (2) N windings wound around at least a portion of the magnetic core and electrically coupled to conductors of the substrate, where N is an integer greater than zero, and (3) a ground return conductor disposed on an outer surface of the magnetic core facing the first portion of the outer surface of the substrate. The at least one electrical component is disposed on the first portion of the outer surface of the substrate.
