Mechanisms and failure modes according to the stress in an electrolytic capacitor. A normal use of the capacitor leads to the evaporation of the electrolyte and the repair of the oxide layer. These are two causes of electrolyte disappearance, which is the main cause of capacitor degradation under normal conditions.
As seen previously, the voltage can influence the aging of the capacitors by applying a voltage overstress in order to subject the capacitor to continuous charge and discharge cycles. The purpose of this experiment is to study the effect of high voltage stress on degradation of the capacitor in .
It has been seen that normal use leads to the evaporation of the electrolyte and the repair of the oxide layer. These are two causes of electrolyte disappearance, which is therefore the essential cause of capacitor degradation under normal conditions. The physical consequences are: increase of ESR and decrease of C.
Increased current ripple in capacitors is considered a criterion for failure. Time to failure can be calculated under variable temperature operating conditions. It is possible to observe methods that include the impact of voltage in addition to using temperature as a stress. Temperature is considered a major constraint, but it is not the only one.
