Abstract
We developed a new type of tantalum solid electrolytic capacitor using poly (3,4-ethylenedioxythiophene) (PEDOT) as a counter electrode. The polymer co unter electrode was formed on a sintered and anodized tantalum substrate by chemical polymerization. The capacitor was characterized by excellent freq uency characteristics and superior durability, due to which it functioned w ithout any deterioration for more than 1000 h at 125 degrees C in air and a t 85 degrees C/85%RH.
