Power Failure: Capacitors are crucial for smoothing out voltage fluctuations in power supplies. A failed capacitor can lead to power failures or, in severe cases, damage to the power supply. Audio Noise: Audio equipment capacitors are used for signal coupling and noise filtering. Failure can introduce noise or distortions in the audio output.
A capacitor can be mechanically destroyed or may malfunction if it is not designed, manufactured, or installed to meet the vibration, shock or acceleration requirement within a particular application. Movement of the capacitor within the case can cause low I.R., shorts or opens.
Mica and tantalum capacitors are more likely to fail in the early period of use (early failure), while aluminum electrolytic capacitors are more likely to experience wear-out failure due to aging use. In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal.
The capacitor may be worn out, and continued use without replacement may result in an open failure or short circuit. Snap mount type aluminum electrolytic capacitors are used in power supply devices. The heat sink and the top of the capacitor were placed close together to reduce the thickness of the device.
Such failures can be avoided with preventive maintenance action such as replacing the capacitor. For film capacitors, the typical failure mode is capacitance decrease due to self-healing, so it is possible to diagnose the life expectancy by understanding the capacitance change.
For example, a failing capacitor can affect the DC output level of a DC power supply because it can’t effectively filter the pulsating rectified voltage as intended. This results in a lower average DC voltage and causes a corresponding erratic behavior due to unwanted ripple – as opposed to the expected clean DC voltage at the load.

This things are a pain, they are very stiff and usually break if you try to move them. This happened to me, so I got a pair of long nose pliers and applied a little ''persuasion'' …
When a capacitor goes bad, it''s often the ESR (equivalent series resistance) that''s out of spec, not the capacitance. Simply put, the cap can still store the same amount of energy, but …
When a capacitor has been damaged or gone bad, it can no longer store the same amount of energy it used to and so the power that goes through the circuit becomes too …
