  • Publication number: 20230352241
    Abstract: A multilayer electrical component including a plurality of parallel plate electrodes embedded in a dielectric body between first and second conductive terminations is disclosed. The dielectric body and the plurality of parallel plate electrodes form a plurality of capacitive layers each comprising a series of capacitors between the first and second conductive terminations. Each capacitor of the capacitive layers is partly defined by a gap in one of the parallel plate electrodes, wherein a gap of the one capacitive layer is laterally offset relative to a gap of an adjacent capacitive layer and a total capacitance of the adjacent capacitive layers is equivalent.

  • Patent number: 11670453
    Abstract: An electrical component having a layered structure including first and second electrodes each having first and second electrode portions located in a plane and at least partially embedded in a dielectric body, each of the first and second electrode portions separated by a gap and substantially isolated by the dielectric, the first electrode substantially parallel to and at least partially overlapping the second electrode, wherein the first and second electrodes are electrically isolated and separated by the dielectric body.

  • Patent number: 11664163
    Abstract: A capacitor comprises a body of dielectric material in which an anode and a cathode are arranged in a stack. A capacitance-forming layer of the dielectric material is arranged between the anode and the cathode. The capacitor further comprises an electro-mechanical connection, which comprises a hole which extends into the body in the direction of the stack. The hole includes an electrical connector. The electrical connector is in electrical contact with either the anode or the cathode, comprises a compliant element, and is suitable for holding a contact pin. The compliant element is configured to decouple the body from mechanical forces applied to the contact pin. The compliant element reduces mechanical stresses experienced by the body of the capacitor. Also provided is a capacitor assembly comprising two or more such capacitors; a kit for assembling such capacitors, and the use of an electrical termination to protect a capacitor from stress.

  • Patent number: 9847176
    Abstract: A dielectric material suitable for use in an electronic component includes bismuth ferrite, strontium titanate and an additive. The additive comprises barium titanate. The barium titanate reduces the temperature capacitance change of the dielectric material and allows for increased working voltages. The material is useful for the construction of capacitors, and particularly capacitors intended for use at high temperatures. Also provided are a capacitor including the dielectric material, methods of manufacturing the dielectric material and the capacitor, and the use of an additive to improve the lifetime and/or reduce the dissipation factor of a capacitor.
