Abstract

Flow through capacitors (300) are described herein having improved capabilities. In general, asymmetric flow through capacitors are formed, increasing overall capacitance. The asymmetry may be accomplished by utilizing electrodes (310, 320) of different materials, different dimensions, or the same materials with different capacitance properties.
