The life of MLCC is affected by temperature conditions and applied DC voltage conditions, and can be expressed by the following acceleration equation.
For example, the high temperature load test at 85ºC and 16V is an accelerated test that is 2,374.16 times higher than the 65ºC 4V environment. The MTTF (40pcs test samples, with a confidence level of 60%) is expected to be 103,562,200h, and the FIT is expected to be 9.656. The n and Ea used in the formula will vary according to the type and structure of the ceramic material, so each model will be different.
