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

Publication number: 20100025876Abstract: The present invention relates to a method of manufacturing a porous article, in particular the anode of a valve action material based solid state capacitor, comprising the steps of combining a water soluble polymeric binder and particulate material before pressing the particulate material and the subsequent step of removing the binder form the pressed pellet. Thus, the present invention also relates to a method of removing a water soluble polymeric binder from pressed particulate material and to a composition comprising a water soluble polymeric binder for forming the anode of a valve action material based solid state capacitor.Type: ApplicationFiled: June 29, 2007Publication date: February 4, 2010Inventors: Martin Biler, Ivana Zednickova, Tomas Karnik, Zdenek Sita

Patent number: 7532457Abstract: A fused electrolytic capacitor assembly that offers improved performance characteristics in a convenient and space-saving package is provided. More specifically, the fused electrolytic capacitor assembly contains an electrolytic capacitor element and a surface mount fuse that are contained within a case and connected to a common anode termination. During initial production, the electrolytic capacitor element and fuse are connected to the anode termination so that the fuse is bypassed during testing of the individual capacitor element. After testing, the anode termination may be cropped so that the fuse and capacitor element become connected in series. Thus, during use, the fuse will disintegrate in response to an excessive current resulting from a short circuit discharge, which breaks the electrical connection between the capacitor element and limits the likelihood of fire or other damage remaining circuit elements.Type: GrantFiled: January 15, 2007Date of Patent: May 12, 2009Assignee: AVX CorporationInventors: Leos Dvorak, Stanislav Zednicek, Zdenek Sita, Ales Vyroubal, Radek Matousek
