  • Patent number: 9866193
    Abstract: Disclosed are apparatus and methodology for increasing the resonance frequency and useful frequency range of surface mount RC equalizer devices. The presently disclosed subject matter provides improved operational characteristics of generally known such RC equalizer devices by implementing a reverse geometry that relocates the internal termination points, as well as external termination points for such devices, along lateral portions of the assembled device. Such reverse geometry achieves improvements by providing a reduction of the equivalent series inductance (ESL) to provide the increased resonance frequency and useful frequency range.

  • Patent number: 9786440
    Abstract: An anode for use in a high voltage electrolytic capacitor is provided. The anode contains a sintered porous pellet and a leadwire extending therefrom in a longitudinal direction. The pellet is multi-layered to the extent that it contains at least a first layer positioned adjacent to a second layer, both of which extend along the length of the anode. The anode leadwire is embedded within the first layer. For this reason, the first layer has a thickness greater than that of the leadwire. Nevertheless, the use of a separate and distinct second layer adjacent to the first layer can allow each of the layers to be independently pressed using a multi-sided compaction device so that the properties of the anode are not significantly impacted by the presence of the relatively large anode leadwire.

  • Patent number: 9776281
    Abstract: A capacitor containing a solid electrolytic capacitor element including a sintered porous anode body and a relatively large diameter anode lead wire is provided. The lead wire is electrically connected to the anode body for connection to an anode termination. Further, the lead wire has a diameter that is at least about 10% of the height of the porous anode body to improve the points of contact between the anode body and wire to reduce ESR. A portion of the lead wire extends from a surface of the anode body in a longitudinal direction. At least one notch can be formed in the portion of the lead wire that extends from the anode body. The notch can be formed via a laser or by cutting, punching, or sawing and can serve as the point of electrical connection between the anode termination and the lead wire.

  • Patent number: 9767964
    Abstract: A capacitor assembly that is stable under extreme conditions is provided. A capacitor assembly that is capable of achieving a high capacitance and yet remain thermally and mechanically stable under extreme conditions. Even at high capacitance values, good mechanical stability can be achieved by connecting multiple individual capacitor elements to the housing of the assembly. Without intending to be limited by theory, it is believed that the use of multiple elements increases the surface area over which the elements are connected to the housing. Among other things, this allows the elements to dissipate vibrational forces incurred during use over a larger area, which reduces the likelihood of delamination. The capacitor elements are also enclosed and hermetically sealed within a single housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor elements.

  • Patent number: 9672989
    Abstract: A capacitor assembly that is capable of exhibiting good properties under humid conditions. The ability to perform under such conditions is due in part to the use of an intrinsically conductive polymer in the solid electrolyte that contains repeating units having the following formula (I): wherein, R is (CH2)a—O—(CH2)b; a is from 0 to 10; b is from 1 to 18; Z is an anion; and X is a cation. Due to its unique structure, the polymer is not highly sensitive to moisture. Consequently, the resulting capacitor assembly may exhibit excellent electrical properties even when exposed to high humidity levels.
