METHOD AND APPARATUS FOR HIGH VOLTAGE ALUMINUM CAPACITOR DESIGN
First Claim
1. A method of producing an apparatus for use in a patient, comprising:
- etching an anode foil;
anodizing the anode foil;
assembling the anode foil, at least one cathode foil and one or more separators into a capacitor stack adapted to deliver from about 5.3 joules per cubic centimeter of capacitor stack volume to about 6.3 joules per cubic centimeter of capacitor stack volume at a voltage of between about 465 volts to about 620 volts;
inserting the stack into a capacitor case;
inserting the capacitor case into a device housing adapted for implant in a patient;
connecting the capacitor to a component; and
sealing the device housing.
