Abstract
A low leakage electrolytic capacitor includes a winding-type capacitor element, a hybrid electrically conductive medium and a package body. The winding-type capacitor element includes an anode foil, a cathode foil, and a separator interposed between the anode foil and the cathode foil. The hybrid electrically conductive medium is impregnated in the winding-type capacitor element and includes an electrically conductive polymer, an auxiliary polymer, an ion liquid, and a carbon filler. The package body encloses the winding-type capacitor element and the hybrid electrically conductive medium.
