When is the lifespan of aluminum electrolytic capacitors? Basic knowledge materials on capacitors are being offered.
Outline the basic relationship between lifespan and temperature, voltage, and ripple current, and summarize the key points for estimating lifespan!
The rated lifespan L0 of most Al-Ecap capacitors is between 1,000 and 15,000 hours (0.11 to 1.71 years). However, the rated lifespan varies depending on temperature, applied voltage, and ripple current, and the lifespan predictions and acceleration factors differ among manufacturers. This is because not only do the chemical properties of the electrolyte and the topology of the capacitors vary by manufacturer, but the testing methods may also differ. This document includes information on the lifespan of representative capacitors, as well as how to choose and use them, failure modes, and failure mechanisms. We encourage you to read it.
