6 FAQs about [Post-processing of polypropylene film for capacitors]
What are metallized polypropylene film capacitors?
Metallized polypropylene film capacitors (MPPFCs) offer numerous advantages, including low dielectric loss, high power density, long cycling life, rapid charge–discharge capabilities, and excellent temperature stability. These attributes make MPPFCs the preferred choice for high-voltage, high-capacity power electronic systems [1, 2].
Does self-healing damage metallized polypropylene film capacitors?
Author to whom correspondence should be addressed. 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.
Do metalized polypropylene film capacitors degrade at high temperatures?
Metalized polypropylene film capacitors (from device to dielectric film) generally degrade at elevated temperatures. Therefore, there is a need to investigate the thermal aging performance of BOPP films across a wide temperature range.
