  • Patent number: 10587049
    Abstract: 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.

  • Patent number: 10588250
    Abstract: The present disclosure relates to a magnetic shielding tape, which is capable of shielding a high-to-low frequency of a signal transmitted through a cable in shielding of a magnetic field which flows in such a cable or is emitted therefrom, and a method for manufacturing the same. The basic magnetic shielding tape comprises: —a thin film magnetic layer including at least one metal ribbon sheet which is divided into a plurality of fine pieces by flaking process, and a gap provided between adjacent fine pieces among the plurality of fine pieces; —a cover film layer adhered to one side surface of the thin film magnetic layer through a first adhesive layer; and—a conductive layer adhered to the other side surface of the thin film magnetic layer through a second adhesive layer, wherein a size of the gap is determined according to a frequency band of the signal.

  • Publication number: 20200076232
    Abstract: A coil for transfer of information or energy is described. The coil includes an electrically conductive magnetically insulative first layer and a magnetically conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer may be substantially co-extensive with a respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. At least one of the opposing longitudinal edge surfaces may include a regular pattern extending substantially along a same first direction and across substantially the entire coil. A method of making the coil is described.

  • Publication number: 20180359885
    Abstract: 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 gaps. At least some of the gaps are filled with an inorganic dielectric material. The gaps at least partially suppress 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.
