In addition, it is capable of providing overload protection for power supplies.

Working Principle

The working principle behind film capacitors such as the MKT1820656255 is based on the dielectric properties of the paper or plastic film layer. A dielectric, when subjected to an electric field, will become polarized, storing and releasing electrical energy as the electric field changes. This behavior can be used to construct a capacitor. When a plate of metal is placed on each side of the film, a Capacitor is created. As an AC current is applied, the electric field across the film oscillates, charging and discharging the capacitor in a similar way.

The advantage of film capacitors, and the reason they are so useful, is that the film layer is able to handle much more power than other types of capacitors, while maintaining a stable capacitance. This makes them ideal for use in high power AC power applications. In addition, they are able to handle higher temperatures than other types of capacitors, ensuring their reliability over an long lifetime.

Conclusion

The MKT1820656255 film capacitor is an ideal solution for a wide range of AC power applications, providing reliable performance over a wide temperature range. Its high-power capability and superior temperature resistance make it suitable for a variety of industrial, consumer and medical applications. Additionally, its ability to provide power factor and harmonic content correction, as well as surge suppression and filtering capabilities, make it an excellent choice for a wide range of applications.
