Patent ID: 7157671

Claim:
A capacitor comprising: a first flat stack of capacitive elements where each element comprises flat anode plate and a flat cathode plate with an electrolyte interposed therebetween; and, a second flat stack of capacitive elements, wherein the first and second flat stacks are enclosed in separate compartments of a capacitor case that electrically isolate the electrolytes of each flat stack from one another, wherein the first and second stacks are in their separate compartments having a common wall, and wherein a cathode terminal of the first stack and a anode terminal of the second stack are electrically connected to the capacitor case such that the capacitance between an anode terminal of the first stack and a cathode terminal of the second stack is equivalent to the capacitance of each stack connected in series, the capacitor case being conductive and serving as an electrical connection between the stacks.
