Film capacitors, also known as plastic film capacitors, are capacitors characterized by their use of a thin plastic film as the dielectric. These types of capacitors were created to have maximum capacitance within a limited space and to provide better stability and larger working voltages than ceramic or paper capacitors.

The MKP383415025JC02R0 is a typical example of a general-purpose, metallized polyester film capacitor. With its excellent insulation and dielectric strength, the MKP383415025JC02R0 is a suitable choice for AC motor drives, PLC circuits and other high-voltage applications that require a capacitor with a long lifespan.

The MKP383415025JC02R0 is a radiation-resistant metallized polyester capacitor, with a nominal capacitance of 4.7 µF, a working voltage of 250VAC and a rated temperature range of -25 to +85°C. Its maximum permissible ripple is 5mArms and its frequency range is 0-120Hz. The capacitor features a safety air gap between terminals, a pre-applied self-healing polyester dielectric and an impregnated oil-filled chamber for additional protection.

Working principle:

The working principle of the MKP383415025JC02R0 can be summarized as follows. When an external voltage is applied, a current will flow through the capacitor. This current creates an electric field across the capacitor plates which sets up an electric force to oppose the applied voltage. This opposition to the applied voltage is known as the capacitance. The more charge that can be stored on the plates of the capacitor, the higher the capacitance.

The metallized polyester film in the MKP383415025JC02R0 acts as a dielectric material between the two metal plates. When a voltage is applied, the electrons flow through the dielectric material, creating an electric field. This electric field sets up an opposing force to the applied voltage, which is referred to as the capacitance.

In addition to providing a barrier between the capacitor plates, the metallized polyester film also imparts certain electrical characteristics that affect the capacitor’s performance. These characteristics include stability, loss, leakage current, and temperature coefficient of capacitance. The combination of all these electrical characteristics provides the MKP383415025JC02R0 with a long lifespan, making it suitable for long-term use in a variety of applications.
