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 powder may have a high specific charge and in turn a relative dense packing configuration. Despite being formed from such a powder, a manganese precursor solution can be readily impregnated into the pores of the anode. This is accomplished, in part, through the use of a dispersant in the precursor solution that helps minimize the likelihood that the manganese oxide precursor will form droplets upon contacting the surface of the dielectric. 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.
