Abstract:
1. A method for forming a hermetically sealed capacitor comprising: forming an anode; forming a dielectric on said anode; forming a conductive layer on said dielectric thereby forming a capacitive element; inserting said capacitive element into a casing; electrically connecting said anode to an exterior anode connection; electrically connecting said cathode to an exterior cathode connection; filling said casing with an atmosphere comprising a composition, based on 1 kg of atmosphere, of at least 175 g to no more than 245 g of oxygen, at least 7 g to no more than 11 g of water, at least 734 grams to no more than 818 grams of nitrogen and no more than 10 grams of a minor component; and hermetically sealing said casing with said atmosphere with said capacitive element contained in said casing.
