ABSTRACT:
During operation of a solid electrolytic capacitor having manganese dioxide as a semiconductor compound, the impedance and the loss factor increase whereas the capacitance decreases. This can be attributed to a dissociation of the manganese dioxide, in which process oxygen is released which attacks the housing. This is obviated by introducing MnO.sub.2 powder in the housing, either in loose form or, preferably, by dispersing finely distributed manganese-dioxide powder in the material of the housing.
