The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some …
Capacitor plague
OverviewHistorySymptomsInvestigationSee alsoFurther reading
The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors between 1999 and 2007, especially those from some Taiwanese manufacturers, due to faulty electrolyte composition that caused corrosion accompanied by gas generation; this often resulted in rupturing of the case of the capacitor from the build-up of pressure.
What Is A Typical Sign That A Capacitor Is Bad Or Has Failed?
Capacitors, when failing, often exhibit distinct physical signs that can be spotted carefully. Here, we expand on the key visual indicators of capacitor failure. Bulging or Swollen Top. …
