  • Patent number: 12046422
    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: 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.
