Capacitor failures can be described by two basic failure categories: catastrophic failures and degraded failures. Catastrophic failure is the complete loss of function of the capacitor in a circuit. Catastrophic failure, such as open or short circuit, is the complete loss of function of the capacitor.
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.
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.
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 time these corrosive species can damage capacitors by removing film metallization, and occasionally the corrosion isolates the film from the end metallisation causing a complete open circuit failure, possibly involving overheating as the ESR increases during the failure process.
