An apparatus comprises an inductor module including: a module substrate including a magnetic dielectric material; a plurality of inductive circuit elements arranged in the module substrate, wherein aninductive circuit element includes conductive traces arranged as a coil including a first coil end, a second coil end and a coil core, wherein the coil core includes the magnetic dielectric material;and a plurality of conductive contact pads electrically coupled to the first and second coil ends. The contact pads electrically coupled to the first coil ends are arranged on a first surface of theinductor module, and the contact pads electrically coupled to the second coil ends are arranged on a second surface of the inductor module.
