Abstract: A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains an anode body that contains tantalum, a dielectric that overlies the anode body; and a solid electrolyte that overlies the dielectric. The solid electrolyte includes an intrinsically conductive polymer containing repeating thiophene units. Further, the capacitor exhibits a dielectric strength of about 0.6 volts per nanometer or more. The capacitor also exhibits a charge-discharge capacitance after being subjected to 3,000 cycles of a surge voltage and an initial capacitance prior to being subjected to the surge voltage, wherein the ratio of the charge-discharge capacitance to the initial capacitance is from about 0.75 to 1.

Abstract: A multilayer electronic device may include a plurality of dielectric layers stacked in a Z-direction that is perpendicular to an X-Y plane. The device may include a first conductive layer overlying one of the plurality of dielectric layers. The multilayer electronic device may include a second conductive layer overlying another of the plurality of dielectric layers and spaced apart from the first conductive layer in the Z-direction. The second conductive layer may overlap the first conductive layer in the X-Y plane at an overlapping area to form a capacitor. The first conductive layer may have a pair of parallel edges at a boundary of the overlapping area and an offset edge within the overlapping area that is parallel with the pair of parallel edges. An offset distance between the offset edge and at least one of the pair of parallel edges may be less than about 500 microns.

Abstract: A high frequency, stripline filter may have a bottom surface for mounting to a mounting surface. The filter may include a monolithic base substrate having a top surface and a plurality of thin-film microstrips, including a first thin-film microstrip and a second thin-film microstrip, formed over the top surface of the substrate. Each of the plurality of thin-film microstrips may have a first arm, a second arm parallel to the first arm, and a base portion connected with the first and second arms. A port may be exposed along the bottom surface of the filter. A conductive path may include a via formed in the substrate. The conductive path may electrically connect the first thin-film microstrip with the port on the bottom surface of the filter. The filter may exhibit an insertion loss that is greater than −3.5 dB at a frequency that is greater than about 15 GHz.

Abstract: A multilayer capacitor may include a monolithic body including a plurality of dielectric layers. A first external terminal may be disposed along a first end, and a second external terminal may be disposed along a second end of the capacitor. The external terminals may include respective bottom portions that extend along a bottom surface of the capacitor. The bottom portions of the external terminals may be spaced apart by a bottom external terminal spacing distance. A bottom shield electrode may be arranged within the monolithic body between a plurality of active electrodes and the bottom surface of the capacitor. The bottom shield electrode may be spaced apart from the bottom surface of the capacitor by a bottom-shield-to-bottom distance that may range from about 3 microns to about 100 microns. A ratio of a length of the capacitor to the bottom external terminal spacing distance may be less than about 4.

Abstract: A solid electrolytic capacitor comprising a capacitor element is provided. The capacitor element comprises a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric and that includes conductive polymer particles. The anode body has an exterior surface that spans in a longitudinal direction to define a length of the anode body, wherein at least one channel is recessed into the exterior surface of the anode body. The channel is defined by opposing sidewalls that intersect at a base, wherein the channel has a width of from about 0.4 millimeters to about 3 millimeters and a depth of from about 50 micrometers to about 350 micrometers.
