Abstract
An electrolytic capacitor is provided having a metal-glass-metal hermetic seal and a liquid seal, which protects the hermetic seal from the electrolyte solution in the capacitor. The liquid seal is formed by compressing an elastomeric ring between the underside of the lid of the capacitor and a terminal plate, connected to the capacitor element, whereby compression of the elastomeric seal is maintained by the lead, which connects the terminal plate and a metal post in the hermetic seal.
