When is the lifespan of a vapor-deposited electrode type capacitor? Basic knowledge materials on capacitors are being offered.
The performance of self-healing (SH) varies by manufacturer! A clear explanation of lifespan estimation.
When predicting the lifespan of MF capacitors, tests are conducted under accelerated conditions of voltage and temperature for approximately 2,000 to 3,000 hours. Based on these results, the lifespan when operating under conditions slightly below the operating conditions (derating) is calculated. Each manufacturer generally publishes an expected lifespan of about 100,000 to 150,000 hours (approximately 11 to 15 years). This document includes not only the lifespan of representative capacitors but also the basics of capacitors, failure modes, and failure mechanisms. We encourage you to read it.
