A wound electrolytic capacitance section is housing within a metal can having a plurality of circumferential indentations or ribs. The uppermost rib provides a seat for the capacitor cover. The lowermost rib determines the depth to which the section extends into the can and provides bottom support for the section. At least one intermediate rib provides lateral support for the section and prevents its lateral movement.

In a metal-cased electrolytic capacitor, means permitting the utilization of a conventional metal capacitor can of a given length so as to house a capacitance section of a newer and shorter length than said can, said means including a convolutely-wound capacitance section having high capacitance anode foil and cathode foil wound with interleaved spacer material to the same diameter as said can, said section being shorter than said can and being located within said can having a bottom as a housing, said can having at least three circumferential indentations, one of said indentations being uppermost and providing a seat for a cover for final sealing of said capacitor, another of said indentations being lowermost and spaced from said bottom of said can and providing support beneath an end of said section around its circumference thereby limiting said section to extend into aid can only to a fixed predetermined depth, and at least one other of said indentations between said uppermost indentation and said lowermost indentation providing lateral support for and preventing lateral movement of said section.
