ABSTRACT:
A wound multi-anodic electrolytic capacitor has a multi-anode stack of strips of high foil gain tunnel-etched aluminum. Inner end edges the anodes in a multi-anode stack are offset from each other by a predetermined distance. Offsetting the end edges of the anodes advantageously reduces mechanical stresses in the capacitor windings. This increases the reliability of the capacitor and advantageously allows a smaller diameter mandrel opening, increasing the energy density per unit volume of the capacitor and allowing its volume to be reduced. When used in an implantable defibrillator or other cardiac rhythm management device, the smaller capacitor advantageously reduces its volume or, alternatively, allows the use of a larger battery, thereby prolonging its useable life.
