Common and less well known failure modes associated with capacitor manufacture defects, device and product assembly problems, inappropriate specification for the application, and product misuse are discussed for ceramic, aluminium electrolytic, tantalum
For capacitors, typically high leakage or short condition results from either dielectric compromise or bridging across the positive and negative terminals, what causes this and how it occurs varies for the different CAPS. High ESR, low or no capacitance typically result from compromised connections, the cause of which varies depending on the
Some of the causes of capacitor trouble are listed below. Transient surges, incurred as a result of switching operations, malfunction of associated circuits or components when of sufficient duration and amplitude produce dielectric failure, permanent shift in capacitance, and failure of seals.
Capacitor failure is a significant concern in electronics, as these components play a critical role in the functionality and longevity of electronic circuits. Understanding the nuances of capacitor failure is essential for diagnosing issues in electronic devices and implementing effective solutions.
Normally, the top of these capacitors is flat, but as they fail, the top can dome or bulge outward. Causes: This bulging is typically due to gas buildup inside the capacitor. The gas is produced when the electrolyte inside the capacitor begins to break down due to overheating, overvoltage, or age-related wear.
Underlying Issues: This overheating can be due to internal failure within the capacitor or external factors such as a malfunctioning component in the circuit. It’s a sign that the capacitor has been operating under stress and may have already failed or is close to failing.
Continued operation of the capacitor can result in increased end termination resistance, additional heating, and eventual failure. The "open" condition is caused by a separation of the end-connection of the capacitor. This condition occurs more often with capacitors of low capacitance and a diameter of less than .25 inch.
The open circuit failure mode results in an almost complete loss of capacitance. The high ESR failure can result in self heating of the capacitor which leads to an increase of internal pressure in the case and loss of electrolyte as the case seal fails and areas local to the capacitor are contaminated with acidic liquid.
