Abstract: A solid electrolytic capacitor that contains an anode body formed from an electrically conductive powder and a dielectric coating located over and/or within the anode body is provided. The present inventors have discovered a technique that is believed to substantially improve the uniformity and consistency of the manganese oxide layer.

Instead, the precursor solution can be better dispersed so that the resulting manganese oxide has a “film-like” configuration and coats at least a portion of the anode in a substantially uniform manner. This improves the quality of the resulting oxide as well as its surface coverage, and thereby enhances the electrical performance of the capacitor.
