  • Solid Electrolytic Capacitor Containing A Deoxidized Anode
    Publication number: 20220093344
    Abstract: A capacitor that comprises a capacitor element is provided. The capacitor element comprises a deoxidized and sintered anode body that is formed from a powder having a specific charge of about 35,000 ?F*V/g or more. Further, a dielectric overlies the anode body and a solid electrolyte overlies the dielectric. The capacitor also exhibits a normalized aged leakage current of about 0.1% or less.
