Accelerated ageing tests for predicting capacitor lifetimes

Being reliability critical components, and widely used in electronics today, electrolytic aluminum capacitors are one of the most likely components to fail under extreme working conditions. Therefore in safety critical applications, their lifetime prediction is of vital importance. The following paper analyses current prediction algorithms and offers an improved solution for capacitor lifetime prediction. The results are obtained from accelerated ageing tests and theoretical data obtained from calculi are compared to real world data obtained from measurements.
