An excessive capacitance.
In the test of service life, the capacitance will not change much when the voltage is heated for a long time. If the capacitance value rises suddenly, the reason can only be judged as a short circuit caused by the breakdown of the capacitor component part. This is because capacitors are composed of many components in series, if the number of serial segments decreases, the capacitance will increase; in contrast, the decrease in capacitance is due to a partial component of open circuit.
