Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT).

Multilayer ceramic capacitors (MLCC) are essential components for determining the reliability of electronic components in terms of time to failure. It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. In this present work, we analyzed the lifetime of three similar X7R type MLCCs based on BaTiO₃ by conducting High Accelerated Life Tests (HALT) at temperatures up to 200 °C at 400 V and 600 V.
