Working Principle

A film capacitor operates on the same principles as any other capacitor, storing electrical energy in an electric field supplied by a voltage source. A film capacitor is known as a non-polarized capacitor, meaning it can be used in both AC and DC circuits. The dielectric material used in a film capacitor is usually a thin, heat resistive, mechanically strong film of polypropylene, which acts as an insulator while providing a strong electric field.

In a typical film capacitor, the capacitor plates are metalized on both sides of the polypropylene film, causing the dielectric to become part of the electric field created. This type of metalization is known as anodizing, in which an anode is placed between the two metalized plates and an electrostatic charge is applied.

The anodizing process creates a metalized film of polyethylene, which creates the electric field that stores the electrical energy in the capacitor. The greater the voltage, the more electric field is created, and the higher the capacitance will be. The charge stored in the electric field will stay in the capacitor until it is discharged, either by a resistor or by the circuit itself.

The MMK5102K63J01L4BULK can also be used in circuits for power factor correction (PFC), pulse power, and voltage bypass. It is a versatile and reliable capacitor, capable of handling high voltage applications with ease.
