Capacitors are at risk of damage in transit or even in storage, well before they are implemented in a design. If a capacitor becomes damaged, either externally or internally, there is a good chance that it will fail. When transporting components, rough handling can damage boxes.
However, excessive electrical, mechanical, or operating environment stresses or design flaws during the manufacture or use of electronic equipment cloud give rise to capacitor failure, smoke, ignition, or other problems. This paper describes failure modes and failure mechanisms with a focus on Al-Ecap, MF-cap, and MLCC used in power electronics.
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.
In the case of film capacitors, when a local short circuit failure occurs, the shorted area may temporarily self-heal. An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit.
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.
Capacitors are at great risk for failure. While it is certain that over time some wear out and no longer adequately serve their purpose, capacitors can also fail prematurely. This article will show the various points where capacitors can be damaged and are at the highest risk of failure.
