The working principle of a film capacitor is based on the same fundamental principles as those of other types of capacitors—namely, the physical concept of capacitance. Capacitors can store electrical energy in the form of static electric charge. When an external voltage is applied across its terminals, the capacitor stores the electric charge, and its capacitance increases. This capacitance is determined by the amount of electric charge stored and the applied voltage.

The MKT1820422404G capacitor, being a film-based capacitor, has a higher dielectric constant, which improves its capacitance. This means that it can store more charge than a regular capacitor with the same size. In addition, the dielectric in a film capacitor is highly stable and resistant to changes in temperature, humidity, and other environmental factors, which helps to improve its reliability and longevity.

Overall, the MKT1820422404G capacitor is an effective and reliable component that is suitable for a variety of power supply circuits. It has a wide range of applications, a large capacitance value, and a wide temperature range for reliable performance. Furthermore, its high dielectric constant and stability help it to improve its capacitance and reliability. As such, the MKT1820422404G capacitor is a popular choice for numerous electronic applications.
