Reliability of high energy density ceramic capacitors

This paper discusses the reliability of the high energy storage density ceramic capacitor full of concept, and points out the failure modes and the possible causes. Failure analysis and reliability evaluation for ceramic capacitors are also given. The failure modes and failure mechanisms were studied in order to estimate component life and failure rate, and the failure criticality is considered to estimate failure effect, which provide information feedback and ensure the quality of the products. The research results can be applied as references to the estimation. In the end, a simple proposal is put forward, and particular emphasis should be placed on breakdown phenomena.
