  • Patent number: 11462361
    Abstract: A capacitor assembly includes a capacitor having ends. A terminal covers less than an area of one end. A wire bond has opposing ends with one end being coupled to the terminal and is configured to break connection with a circuit when an electrical current through the wire bond reaches a fusing current. An energy storage module includes at least two capacitor assemblies. The wire bond of one capacitor is electrically connected to the second terminal of an adjacent capacitor. An energy storage assembly includes two energy storage modules stacked one on top of the other. A pulse forming network includes conductors and at least two energy storage modules. A method of making a module includes charging each of the capacitors, removing each capacitor that fails, connecting one end of a wire bond to one terminal and connecting the other end to an adjacent capacitor or to a conductor.

  • Patent number: 10741330
    Abstract: A multilayer chip capacitor includes electrodes comprised of numerous, closely spaced conductive layers. Adjacent conductive layers are essentially non-overlapping, so that fringe capacitance between opposing electrodes provides substantially all of the capacitance. The conductive layers may be shaped to form a non-planer boundary between electrodes. An additional high frequency integrated capacitor is formed from external electrode plates. The non-planar electrode boundary principle is also applied to discoidal capacitors in the form of a non-concentric electrode boundary.

  • Patent number: 8974654
    Abstract: A multilayer ceramic capacitor and method of creating are provided. The capacitor includes a plurality of interior plates having edges that are brought to and exposed upon a first surface and also upon a portion of a second surface of the capacitor at a region where the second surface meets the first surface. An electroplated terminal is directly in contact with and mechanically and electrically connected to an edge of each of the interior plates where each plate's edge is exposed upon the first surface. The terminal wraps over the region of the capacitor from the first surface onto the portion of the second surface and is directly in contact with and mechanically and electrically connected to an edge of each of the interior plates where each plate's edge is exposed upon the second surface. The terminal does not extend to any additional surfaces which meet the first surface.

  • Patent number: 8163331
    Abstract: A terminal to, most commonly, a ceramic capacitor, most commonly a multilayer ceramic capacitor (MLCC), is formed by electroless plating, also known as electroless deposition or simply as electrodeposition. In the MLCC having a multiple parallel interior plates brought to, and exposed at, at least one, first, surface, an electrically-conductive first-metal layer, preferably Cu, is electrolessly deposited upon this first surface directly in contact with, mechanically connected to, and electrically connected to, the edges of these interior plates. Lateral growth of the electrolessly-deposited first-metal is sufficient to span from exposed plate to exposed plate, electrically connecting the plates. One or more top layers, preferably one of Ni and one of Sn and Pb, are deposited, preferably by plating and more preferably by electrolytic plating, on top of the electrolessly-deposited Cu.

  • Patent number: 6974516
    Abstract: A method of fabricating a ceramic tube with electrodes thereon suitable for use as a tubular reaction chamber for a fuel cell. In one embodiment, the method includes wrapping a first electrode material around a mandrel, then wrapping a green ceramic material over the first electrode material, and then wrapping a second electrode material over the green ceramic material. The wrapped layers are laminated together, and then removed from the mandrel and sintered, in either sequence, to produce the laminated ceramic tube having an inner first electrode and an outer second electrode. Alternatively, a first electrode tube is provided in place of the mandrel and around which the green ceramic material is wrapped. The outer second electrode may be produced by wrapping a second electrode material around the green ceramic material, before or after laminating, or by printing the electrode material onto the sintered ceramic tube.
