15 Examples of Causes and Countermeasures for Capacitor Failures (with Diagrams)

15 Examples of Causes and Countermeasures for Capacitor Failures (with Diagrams)

To ensure that our capacitors are used with higher reliability, we would like to introduce some examples of troubles.

When a capacitor fails, electronic devices may not operate as expected, potentially leading to unexpected accidents. However, it is impossible to eliminate capacitor failures entirely. Therefore, our company, which has been manufacturing capacitors for about 70 years, will introduce the causes of failures and examples of countermeasures to ensure that capacitors are used appropriately and safely. [Failure Phenomena and Examples, Causes and Countermeasures] ■ Smoke emitted from a capacitor that shorted due to overvoltage ■ A capacitor failed due to excessive ripple, causing electrolyte to spray out ■ A capacitor in the charge and discharge circuit lost its capacitance ■ A pressure valve failed to operate, causing steam to erupt from the grounding surface ■ One of the capacitors connected in parallel failed ■ The characteristics of an aluminum electrolytic capacitor decreased at low temperatures ■ The characteristics of an aluminum electrolytic capacitor deteriorated after long-term storage ■ An aluminum electrolytic capacitor sparked ■ An aluminum electrolytic capacitor installed horizontally burst ■ An aluminum electrolytic capacitor connected in series shorted ■ A film capacitor intended for DC use failed when used in an AC circuit ■ A resin-coated film capacitor ignited *For more details, please refer to the PDF document or feel free to contact us.
