Metallized polypropylene film capacitors are known to be one of the most common causes of failure in electronic systems. Predicting their lifetime to anticipate failures is a key issue in the assessment of these systems' reliability. In this paper, accelerated ageing tests applying voltage, temperature and humidity were conducted on 42 capacitors.

Self-healing (SH) in metallized polypropylene film capacitors (MPPFCs) can lead to irreversible damage to electrode and dielectric structures, resulting in capacitance loss and significant stability degradation, especially under cumulative SH conditions.
Polyester capacitors are regarded as “general purpose capacitors”. They provide the best volume efficiency of all film capacitors at moderate cost and are preferably used for DC applications such as decoupling, blocking, bypassing and noise suppressions. Polypropylene film has superior electrical characteristics.
The accelerated testing is an important method to investigate the reliability performance of DC film capacitors. In , the aging of metallized polymer capacitors has been studied under accelerated testing conditions of voltage and temperature.
The analysis of the film and metallization layer is performed for a degraded capacitor sample and a new capacitor sample by visual inspection, optical microscopy, and energy-dispersive x-ray (EDX) spectroscopy. 2.
