Abstract:
1. An electrolytic capacitor stack disposed in a case, the case filled with electrolyte, comprising: a first substantially planar electrode having a first perimeter and a first thickness; a second substantially planar electrode having a second perimeter and a second thickness, the second thickness from about 3 times the first thickness to about 14 times the first thickness, the second substantially planar electrode in a stack with the first substantially planar electrode; and a first substantially planar separator having a separator perimeter and a first separator thickness from about 0.4 times the first thickness to about 1.0 times the first thickness, the first substantially planar separator disposed between the first substantially planar electrode and the second substantially planar electrode; wherein the first perimeter is laterally disposed outside the separator perimeter along a first section of the separator perimeter and the second perimeter is laterally disposed inside the separator perimeter along the first section by an isolation distance, the isolation distance from more than one times the first separator thickness to at least three times the first separator thickness.
