Abstract: The present subject matter includes a capacitor stack having at least one cathode layer, and at least one anode layer. Separator paper is shaped and sized to separate the anode and the cathode and resist breakdown. The capacitor stack is compact, and is adapted for use in compact devices. For example, the capacitor stack is adapted for use in cardiac rhythm management devices which are implanted.

Abstract: One aspect provides a capacitor feedthrough assembly having an electrically conductive member dimensioned to extend at least partially through a feedthrough hole of a case of the capacitor, the conductive member having a passage therethrough.

Abstract: A method includes connecting together one or more anode connection members of one or more anode foils and one or more cathode connection members of one or more cathode foils and electrically isolating the one or more anode foils from the one or more cathode foils. A capacitor stack includes a plurality of cathode layers having cathode connection members and a plurality of anode layers having anode connection members. The anode connection members are connected to the cathode connection members and configured such that the anode layers can be electrically separated from the cathode layers by cutting only the anode connection members or the cathode connection members.

Abstract: In one aspect, a method of manufacturing a capacitor includes disposing one or more conductive layers of a first electrode stack in a recess of an alignment mechanism, where the recess is positioned relative to two or more alignment elements. The method further includes placing a separator over the one or more conductive layers where an outer edge of the separator contacts the two or more alignment elements. In one embodiment, a capacitor includes anode and cathode foils having offsetting edge portions. In one embodiment, a multiple tab cathode for a flat capacitor. A plurality of cathode tabs are portioned into a plurality of cathode tab groups positioned in different locations along the edge of the capacitor stack to reduce the amount of space required for connecting and routing the cathode tabs.
