Filed: 1993-12-28
Abstract: PURPOSE:To prevent breakage and bursting caused by pressure of hydrogen gas which is mainly generated while an electrolytic capacitor is used by providing a capacitor with a transmitting film consisting of polysulfide-modified epoxy resin. CONSTITUTION:An electrolytic capacitor is provided with a hydrogen gas transmitting film 1 consisting of a polysulfide-modified epoxy resin hardening body.
