Abstract
An all tantalum electrolytic capacitor is rendered non-polar by properly anodizing the tantalum electrodes. That is, the anodization process is controlled such that both electrodes have substantially the same amount of capacitance which preferably is twice the capacitance on the rated capacitance of the capacitor. The anodization voltage is at least greater than the rated voltage of the capacitor.
