Abstract: A multilayer ceramic capacitor is disclosed including a first external terminal disposed along a first end of the capacitor, a second external terminal disposed along a second end of the capacitor opposite the first end, an active electrode region containing alternating dielectric layers and active electrode layers, and a shield electrode region including at least two shield electrodes that are spaced apart by a shield layer gap in the longitudinal direction. The distance from the active electrode region to the shield electrode region may range from about 4% to about 20% of a thickness of the capacitor between a top surface and a bottom surface opposing the top surface. The shield layer gap may range from about 3% to about 60% of an external terminal gap between the first external terminal and second external terminal in the longitudinal direction on at least one of the top or bottom surfaces.

Abstract: A high frequency coupler is disclosed that is configured for grid array-type surface mounting. The coupler includes a monolithic base substrate having a top surface and a bottom surface. A first thin film microstrip and a second thin film microstrip are each disposed on the top surface of the monolithic base substrate. Each microstrip has an input end and an output end. At least one via extends through the monolithic base substrate from the top surface to the bottom surface of the monolithic base substrate. The via(s) are electrically connected with at least one of the input end or the output end of the first microstrip or the second microstrip. The coupler has a coupling factor that is greater than about -30 dB at about 28 GHz.

Abstract: A method is disclosed for making a multilayer electronic device. The method includes placing a screen printing mask on a layer of support material and printing a conductive pattern on a layer of support material using the screen printing mask. The conductive pattern includes a plurality of electrode shapes including respective central enlarged portions. The method includes cutting the layer of support material and conductive pattern along a plurality of cutting lines intersecting the central enlarged portions such that at least one of the plurality of electrode shapes is divided into a pair of electrodes along a cutting width. The cutting width is indicative of a cutting accuracy associated with at least one of the cutting lines.

Abstract: An ultracapacitor that contains at least one electrochemical cell is provided. The cell includes a first electrode that contains a first carbonaceous coating (e.g., activated carbon particles) electrically coupled to a first current collector, a second electrode that contains a second carbonaceous coating (e.g., activated carbon particles) electrically coupled to a second current collector, an aqueous electrolyte in ionic contact with the first electrode and the second electrode and that contains a polyprotic acid (e.g., sulfuric acid), and a separator that is positioned between the first and second electrodes. Through selective control over the particular nature of the materials used to form the ultracapacitor, as well as the manner in which they are formed, a variety of beneficial properties may be achieved.

Abstract: A supercapacitor module is provided. In some implementations, the supercapacitor module may include a first supercapacitor having a first parameter value for a capacitor parameter in a first test condition. The supercapacitor module may include a second supercapacitor having a second parameter value for the capacitor parameter in about the first test condition. A ratio of the second parameter value to the first parameter value may be from about 0.8 to about 1.2. The supercapacitor module may prevent overvoltages across the first and second supercapacitors, such that the supercapacitor module may satisfactorily operate without a balancing circuit.

Abstract: A capacitor assembly that is capable of performing well under the conditions of high humidity (e.g., 60% relative humidity) is provided. The capacitor assembly comprises a solid electrolytic capacitor element that contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. An anode termination is in electrical connection with the anode body and a cathode termination is in electrical connection with the solid electrolyte. A first coating is disposed on at least a portion of the anode termination that contains an organometallic compound and a second coating is disposed on at least a portion of the cathode termination that contains an organometallic compound. Further, a casing material encapsulates the capacitor element and leaves exposed a mounting surface of the anode termination and the cathode termination.

Abstract: A capacitor assembly that is capable of performing well under the conditions of high humidity and temperature (e.g., 85% relative humidity/85C) is provided. The capacitor assembly comprises a solid electrolytic capacitor element, an anode termination that is in electrical connection with the anode body, cathode termination that is in electrical connection with the solid electrolyte, and casing material that encapsulates the capacitor element and leaves exposed at least a portion of the anode termination and the cathode termination. The casing material is formed from an epoxy composition that contains one or more inorganic oxide fillers and a resinous material that includes one or more epoxy resins crosslinked with a co-reactant, wherein inorganic oxide fillers about 75 wt.% or more of the epoxy composition, and vitreous silica constitutes about 30 wt.% or more of the total weight of inorganic oxide fillers in the epoxy composition.
