Abstract

Hermetically sealed electrolytic capacitors eventually lose hermeticity and leak the corrosive electrolyte onto surrounding electronics, thereby lowering system reliability and promoting corrosion.

Endcap for Hermetically Sealed Capacitors

      Hermetically sealed electrolytic capacitors eventually lose
hermeticity and leak the corrosive electrolyte onto surrounding
electronics, thereby lowering system reliability and promoting
corrosion.

      An electrolyte resistant endcap has been designed which when
placed and sealed over the end of the capacitor will provide higher
reliability and longer system performance. Any electrolyte that leaks
through a broken hermetic seal is still retained in the vicinity of
the corrosion resistant capacitor, yet excessive pressures from
device performance which caused the loss of hermeticity are permitted
to leak to atmosphere.

      An example of the endcap is shown in the drawing.
