    摘要： A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by a network of interconnected gaps. The interconnected gaps are at least partially filled with a thermoset dielectric material. The network of interconnected gaps at least partially suppresses electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

    摘要： A cable includes a plurality of conductor sets. Each conductor set extending along a length of the cable and includes two or more insulated conductors, each insulated conductor including a central conductor surrounded by a dielectric material that includes polyolefin, a brominated flame retardant, and antimony trioxide. First and second conductive shielding films are disposed on opposite first and second sides of the conductor set, including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second shielding films in combination substantially surround the conductor set, and the pinched portions of the first and second shielding films in combination form pinched portions of the conductor set on each side of the conductor set. The cable includes an adhesive layer bonding the first shielding film to the second shielding film in the pinched portions of the conductor set.
