It is important that designers understand what causes electrolytic capacitor degradation. When an electrolytic capacitor fails, it can be because of a short circuit, circuit damage, or even an explosion. Most electrolytic capacitor degradation results from a common failure mode: the vaporization or leakage of electrolyte.
Physical Damage: Mechanical stress, vibration, or impact can physically damage capacitors, leading to internal short circuits or breakage of the connections. Aging and Wear: Over time, capacitors naturally degrade. Electrolytic capacitors, in particular, can dry out, losing their ability to store charge effectively.
High operating temperature is one reason that electrolytic capacitors are one of the most commonly failing components in electronics. Figure 4 shows how an electrolytic capacitor is constructed.

Mechanical Stress and Vibration: Physical shocks, mechanical stress, and vibration can damage capacitor components, lead to internal connections or electrode fractures, and result in open or short circuits within the capacitor.
The dielectric breakdown of the oxide layer in electrolytic capacitors develops a short circuit. This failure mode may result from excessive application of operating voltage, reverse voltage, or ripple current.
The failure mode of electrolytic capacitors is relatively slow and manifests over periods of months rather than seconds which can be the case with short circuit capacitor failure modes. Therefore condition monitoring may be practical and useful for these components.
