Film capacitors, also known as plastic, polyester, film dielectric and film capacitor—sometimes referred to as “Dep” capacitor after its original manufacturer—are capacitors that use plastic films, such as polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS)[1], polyphenylene sulfide (PPS), or polyester (PE) as the dielectric medium. The most common type of film capacitors are metallized film capacitors, in which the plastic film is coated with a thin layer of metal.

The FFVS6B1286K is an example of a film capacitor. It is a radial leaded metallized polyester film capacitor with a voltage rating of 275VAC, a capacitance of 0.47uF, and tolerance of 5%. It is usually used for power supply and filtering applications in electronic equipment and power circuits, such as in switch mode power supplies (SMPS), input and output filters in lighting circuits, and for general signal conditioning in motor drive and appliance control circuits.

The working principle of a film capacitor is similar to that of other capacitors in that the device consists of two conducting plates or surfaces, the electrodes, which are separated by a dielectric material (in this case, an insulating plastic film). When a voltage is applied between the two electrodes, an electric field is generated between the two electrodes, which results in the accumulation of positive charge on one plate and of negative charge on the other. This creates an electric field in the dielectric and an electric potential, or capacitance, across the terminals. The result is an electrical storage device that can be used to store an electrical charge.

The main advantage of a film capacitor is that it offers excellent frequency response characteristics, making them well-suited for use in high-frequency applications. The high dielectric strength of the plastic film also enables it to withstand high voltage surges and other transient voltage spikes, making them a suitable choice for protecting equipment from power surges. Additionally, the capacitance of the capacitor is stable over time and temperature, making it a reliable choice for applications that require precise capacitance values.

Overall, film capacitors such as the FFVS6B1286K are versatile and reliable components that offer excellent frequency capabilities and voltage surge protection for a wide range of applications in the electronics industry. They are highly efficient and often used in switch-mode power supplies and in equipment control circuits where precise capacitance values and control over frequencies and voltages are needed.
