Aluminum electrolytic capacitor failure
The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid between 1999 and 2007, especially those from some Taiwanese manufacturers, due to faulty composition that caused accompanied by gas generation; this often resulted in rupturing of the case of the capacitor from the build-up of . It describes the failure mechanisms seen in aluminum electrolytic capacitors and the failure analysis techniques used to identify the failures. It includes figures, equations and graphs. [pdf]
FAQS about Aluminum electrolytic capacitor failure
What happens if aluminum electrolytic capacitors fail?
Failing aluminum electrolytic capacitors can have significantly adverse effects on electronic circuits. Most technicians have seen the tale-tell signs – bulging, chemical leaks, and even tops that have blown off. When they fail, the circuits that contain them no longer perform as designed – most often affecting power supplies.
What is failure mode in a polymer aluminum electrolytic capacitor?
Failure Mode in Market is Open mode mainly. Polymer aluminum electrolytic capacitors slowly degrade due to the usage conditions such as the ambient temperature and humidity.
How long do aluminum electrolytic capacitors last?
Lifetime of aluminum electrolytic capacitors is generally specified as the time under certain con-ditions of applied DC voltage, ripple current, and ambient conditions (temperature, airflow, heatsinking) at which the capacitor’s electrical parameters have drifted out of some specified lim-its.
Why do electrolytic capacitors fail?
High operating temperature is one reason that electrolytic capacitors are one of the most commonly failing components in electronics. Figure 4 shows how an electrolytic capacitor is constructed.

When does a capacitor fail?
Generally, when voltages are applied, the leakage current begins to drop. Finally, at the end of the life span, the capacitor enters an open-circuit mode as the dielectric dries up. The criteria for defining failures are established for each individual product series.
What is a non-solid aluminium electrolytic capacitor?
The non-solid aluminium electrolytic capacitors with improperly formulated electrolyte mostly belonged to the so-called "low equivalent series resistance (ESR)", "low impedance ", or "high ripple current" e-cap series.
