Patent number: 8576544Abstract: A capacitor assembly that includes a conductive polymer electrolytic capacitor that is enclosed and hermetically sealed within a ceramic housing in the presence of an inert gas is provided. Without intending to be limited by theory, the present inventors believe that the ceramic housing is capable of limiting the amount of oxygen and moisture supplied to the conductive polymer of the capacitor. In this manner, the conductive polymer is less likely to oxidize in high temperature environments, thus increasing the thermal stability of the capacitor assembly.Type: GrantFiled: January 9, 2012Date of Patent: November 5, 2013Assignee: AVX CorporationInventors: Bharat Rawal, Gang Ning, Brady Jones, Zebbie Lynn Sebald, Stanislav Zednicek, Zdenek Sita

Patent number: 7824452Abstract: The present invention concerns the field of solid state capacitors and in particular high performance capacitors for use in modern electronic devices. Specifically, the present invention relates to a method by which powders of valve-action material may be modified to make them suitable for use in the formation of capacitor anodes for solid state electrolytic capacitors. According to the present invention there is provided a method of modifying raw valve-action material powder into capacitor grade structured powder comprising: (i) providing a raw powder to be converted; (ii) compressing a portion of the powder to form a porous solid mass of powder (iii) heating the solid mass to a pre-determined sintering temperature and maintaining the temperature for a pre-determined time period to form a sintered body, (iv) pulverising the sintered body to form a processed powder and (v) optionally grading the powder particles within pre-determined size ranges so as to collect capacitor grade powder.Type: GrantFiled: November 9, 2007Date of Patent: November 2, 2010Assignee: AVX LimitedInventors: Brady A. Jones, Colin McCracken, James Fife, Ian Margerison, Tomas Karnik

Patent number: 7649730Abstract: A wet electrolytic capacitor that includes a plurality of anodes, cathode, and working electrolyte that is disposed in electrical contact with the anodes and current collector is provided. Any number of anodes may generally be employed, such as from 2 to 40, in some embodiments from 3 to 30, and in some embodiments, from 4 to 20. The anodes are thin and typically have a thickness of about 1500 micrometers or less, in some embodiments about 1000 micrometers or less, and in some embodiments, from about 50 to about 500 micrometers. By employing a plurality of anodes that are relatively thin in nature, the resulting wet electrolytic capacitor is able to achieve excellent electrical properties.Type: GrantFiled: March 20, 2007Date of Patent: January 19, 2010Assignee: AVX CorporationInventors: Brady Jones, Gang Ning, Bharat Rawal

Publication number: 20080232032Abstract: A capacitor anode that is formed from ceramic particles (e.g., Nb2O5, Ta2O5) capable of being chemically reduced to form an electrically conductive composition (e.g., NbO, Ta) is provided. For instance, a slip composition containing the ceramic particles may be initially formed and deposited onto a carrier substrate in the form of a thin layer. If desired, multiple layers may be formed to achieve the target thickness for the anode. Once formed, the layer(s) are subjected to a heat treatment to chemically reduce the ceramic particles and form the electrically conductive anode. Contrary to conventional press-formed anodes, the slip-formed anodes of the present invention may exhibit a small thickness, high aspect ratio (i.e., ratio of width to thickness), and uniform density, which may in turn may lead to an improved volumetric efficiency and equivalent series resistance (“ESR”).Type: ApplicationFiled: March 20, 2007Publication date: September 25, 2008Applicant: AVX CorporationInventors: Brady Jones, Carl L.
