Abstract:
An electrolytic capacitor comprising:a hermetically sealed capacitor case defining an interior case chamber bounded by a case wall the case further comprising a case base with a case side wall extending from the case base to a side wall upper opening edge, and a cover hermetically sealed at a cover edge against the side wall upper opening edge to enclose the interior case chamber; an electrode stack assembly and electrolyte located within the interior case chamber, the electrode stack assembly further comprising a plurality of capacitor layers stacked in registration upon one another, each capacitor layer comprising a cathode layer having a cathode tab, an anode sub-assembly comprising at least one anode layer having an anode tab, and a separator layer located between adjacent anode and cathode layers, whereby all adjacent cathode layers and anode layers of the stack are electrically insulated from one another by a separator layer; an anode terminal passageway through said case wall; anode terminal means comprising an anode terminal having a first anode terminal end electrically and mechanically connected with a plurality of said anode tabs and a second anode terminal end and means for supporting said anode terminal extending through said anode terminal passageway while electrically insulating said anode terminal from said case wall thereby locating an anode connection terminal at said second anode terminal end exterior to said case wall; a cathode terminal passageway through said case wall; a cathode terminal having a first cathode terminal end electrically and mechanically coupled with a plurality of said cathode tabs and having a second cathode terminal end; means for electrically and mechanically sealing said cathode terminal into said cathode terminal passageway to seal said cathode terminal passageway thereby making electrical connection of said cathode tabs with said case wall and providing a cathode connection terminal at or coupled to the exterior surface of the case wall; and a connector assembly electrically attached to said anode connection terminal for making electrical connection with said anode tabs and electrically attached to said cathode connection terminal for making electrical connection with said cathode tabs.
