Although a quick search will show a number of "segmented metallized film technologies" on the market, they do not all achieve controlled self-healing. Non-optimized segmentation can generate unexpected results, such as loss of controlled self-healing if under segmented or very low lifetime expectancy if over segmented. With 30 years of experience of manufacturing controlled self-healing capacitors, AVX can claim extensive knowledge and experience in this area with proven field reliability and zero catastrophic failures, even under severe usage conditions. These capacitors provide a competitive solution, while maintaining the highest electrical and mechanical specifications and a long lifetime expectancy.
