Abstract
A wet electrolytic capacitor that contains a hermetically sealed lid assembly is disclosed. More specifically, the lid assembly contains a lid (e.g., titanium) that defines an internal orifice. A conductive tube may extend through the orifice that is of a size and shape sufficient to accommodate an anode lead. An insulative material is also provided within the orifice to form a hermetic seal (e.g., glass-to-metal seal), such as between the conductive tube and the lid. The lid assembly also includes a liquid seal that is formed from a sealant material. The liquid seal coats a substantial portion of the lower surface of the lid and hermetic seal to limit contact with any electrolyte that may leak from the casing. To help achieve such surface coverage, the sealant material is generally flowable so that it can be heated during production of the capacitor and flow into small crevices that would otherwise remains uncoated.
