Abstract

A multi-layered conductor comprising one or more conductor layers of an electrically conductive material and one or more shielding layers of a soft magnetic material. The shielding layer can be coated onto the conductor layer and has a lower conductivity and a higher magnetic permeability than the electrically conductive material of conductor layers. The shielding layer can, at least when alternating current (AC) flows through the multi-layered conductor at relatively high frequencies, provide a separate power path for at least a portion of the high frequency AC current, as well as absorb at least a portion of the high frequency noises associated with that separated high frequency AC current. Additionally, the shielding layer can be separated from the conductor layer at an output end of the multi-layered conductor so that output ends of the shielding layer and conductor layer can be electrically connected to different electrical devices or components.
