Thin Film Capacitors
![](/image/categories/thin-film-capacitors.jpg)
Thin Film Capacitors are high performance capacitors using polymer films as medium. The core components of such capacitors consist of two metal foil electrodes and a thin polymer film sandwiched between them, typically made of polypropylene (PP), polyester (PET), or polyphenylene sulfide (PPS). The design principle of thin film capacitor is to use the excellent dielectric properties of polymer film to achieve low loss, high stability, wide operating temperature range and long life. They maintain stable capacitance values at high frequencies and have extremely low dielectric absorption, making them suitable for circuit designs that require high reliability and precision.
