Working Principle
The working principle of a F1778447K3I0W0 film capacitor is based on the electric double layer formed at the interface between the capacitor dielectric and the conductive electrode. This electric double layer is what makes the capacitor capacitive. The F1778447K3I0W0 capacitor uses a film dielectric material, such as Mylar, PP or polystyrene, which is sandwiched between two conductive electrodes. When a voltage is applied at the electrodes, a charge is stored at the electric double layer, and the amount of charge is proportional to the voltage applied. This charge is what produces the capacitance of the capacitor, which is measured in Farads.

Conclusion
The F1778447K3I0W0 is a Dielectric-Film Capacitor, which has many uses in consumer, industrial, and military applications. It has a variety of application fields due to its low-loss characteristics, small size, and high stability and reliability. The working principle of the F1778447K3I0W0 is based on an electric double layer formed at the interface between the dielectric and the conductive electrode, which allows for the capacitor to store a voltage and therefore produce capacitance.
