Thin-film capacitors use PP (polypropylene), PET (polyethylene terephthalate), PPS (polyphenylene sulfide) and PEN (polyethylene naphthalate) as dielectrics, which have the advantages of good stability, high working frequency, low leakage current, reduced circuit power consumption and noise, self-healing and not easy to be damaged, and are often used in computers, digital cameras and so on. In mobile phones, televisions, radios and other communication equipment, it plays the role of isolating signals and adjusting frequencies; In solar panels, lithium batteries and other fields, it helps the circuit stability and energy storage effect.
