High conductivity loss and low breakdown strength of traditional polypropylene (PP) film in the high-temperature environment are the key factors limiting the application of metallised film capacitors (MFCs). The effect of cyclic olefin copolymers (COCs) with different ...
Polystyrene film capacitors also have the lowest dielectric absorption among all capacitor types at 0.02%, making them the go-to components for critical timing circuits and applications. On the flip side, polystyrene capacitors are unsuitable for temperatures exceeding 85 degrees Celsius and are not available in metallized versions.
