    The open circuit failure mode results in an almost complete loss of capacitance. The high ESR failure can result in self heating of the capacitor which leads to an increase of internal pressure in the case and loss of electrolyte as the case seal fails and areas local to the capacitor are contaminated with acidic liquid.

    What causes a hermetically sealed capacitor to fail?

    Fatigue in the leads or mounting brackets can also cause a catastrophic failure. The altitude at which hermetically sealed capacitors are to be operated will control the voltage rating of the capacitor. As the barometric pressure decreases so does the terminal "arc-over" susceptibility increase.

    What is a catastrophic failure of a capacitor?

    Catastrophic failure is the complete loss of function of the capacitor in a circuit. Catastrophic failure, such as open or short circuit, is the complete loss of function of the capacitor.
