Over the history of film capacitors, from a material perspective, the major breakthrough started with the move from paper to polymers, and especially to polypropylene, which finally became the dominant dielectric in film capacitors today.
The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
By using these features, use of film capacitors in an audio circuits provides a benefit of decreased distortion and improved sound quality. While the voltage endurance of aluminum electrolytic capacitors is near 500 V, film capacitor can be used for products with nearly a 4000 V endurance.
General-purpose film capacitors are often made with PP. As you all know, environment-related markets, including inverters used in EVs/HEVs and solar/wind power generation systems are largely expanding. In particular, demand for high-power applications (high voltage exceeding 500 VDC, large capacity) is increasing.
For the performance needed for inverters, film capacitors are often adopted to meet the demand for high voltage endurance, long life, and high reliability. Up to this point, the superiority of film capacitors has been introduced, but they are not superior in all characteristics. One of such characteristic is the capacitance per unit volume.
