Patent number: 9866193Abstract: 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.Type: GrantFiled: April 8, 2016Date of Patent: January 9, 2018Assignee: AVX CorporationInventor: Gheorghe Korony

Patent number: 9786440Abstract: 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.Type: GrantFiled: December 17, 2014Date of Patent: October 10, 2017Assignee: AVX CorporationInventors: Mitchell D.

Patent number: 9767964Abstract: 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.Type: GrantFiled: April 7, 2011Date of Patent: September 19, 2017Assignee: AVX CorporationInventor: Ivana Zednickova

Patent number: 9672989Abstract: 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.Type: GrantFiled: May 29, 2015Date of Patent: June 6, 2017Assignee: AVX CorporationInventors: Miloslav Uher, Jan Petrzilek
