When is the lifespan of a capacitor? A thorough explanation of prediction methods! Basic knowledge materials are currently available.

Factors that influence failure rates and general lifespan estimation formulas are explained in an easy-to-understand manner!

The function of a capacitor is to "not allow direct current to pass," "instantaneously store and release charge," and "allow alternating current to pass." When these functions are lost, it results in failure. The failure rate is defined as "the ratio of a system or component that, after operating without failure for a certain period, experiences a failure within the subsequent unit period." In other words, the failure rate is "the rate at which failures occur" and is a quantitative measure of reliability. This document covers the basics of life estimation, failure modes and mechanisms, selection and usage, among other topics. We encourage you to read it.
