Abstract:
An electrical component including a flat electrolytic capacitor, said capacitor comprising:a plurality of etched and anodized aluminum anode foils, arranged in a stack, each anode foil having a tab which is aligned with the tabs of the other anode foils, said anode foils being etched prior to being anodized;a plurality of aluminum cathode foils interleaved with said anode foils, each cathode foil having a tab which is aligned with the tabs of the other cathode foils;a plurality of spacers interleaved with said anode and cathode foils, each spacer being situated between one of said anode foils and one of said cathode foils;an enclosure surrounding said anode foils and said cathode foils, said enclosure having flat exterior walls parallel to said foils, said tabs protruding from said enclosure;an electrolyte lying between said anode foils and said cathode foils, said electrolyte being contained by said enclosure; anda pair of leads conductively attached to said tabs of respective anode and cathode foils outside of said enclosure,said electrical component further comprising a circuit mounted on said enclosure, said capacitor being incorporated in said circuit by means of said leads.
