A wound multi-anodic electrolytic capacitor has a multi-anode stack of strip s of high foil gain tunnel-etched aluminum. Inner end edges of the anodes (215 A, 215B) 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 reliabilit y of the capacitor and advantageously allows a smaller diameter mandrel openin g, 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 reduc es its volume or, alternatively, allows the use of a larger battery, thereby prolonging its useable life. |
