Film capacitors use metal foils as electrodes, which are stacked on both ends with plastic films such as polyester, polypropylene, polystyrene, or polycarbonate, and then wound into a cylindrical structure to form a capacitor. Film capacitors have many excellent characteristics, making them highly functional capacitors. Their key properties are: non-polarity, very high insulation resistance, excellent frequency characteristics (wide frequency response), and very low dielectric loss. Due to these advantages, film capacitors are widely used in analog circuits. Especially in signal interconnection parts, it is necessary to use capacitors with excellent frequency characteristics and very low dielectric loss to ensure that the signals do not undergo significant distortion during transmission.
Film capacitors are widely used in household appliances, yet consumers rarely pay attention to them, earning them the reputation of being the "best supporting component" in home appliances.
