Film Capacitors

A film capacitor, sometimes known as a plastic or film dielectric capacitor, is a capacitor that uses a plastic film as the dielectric. It is constructed with metal electrodes, which are separated by the dielectric material, having the ability to store electrical energy temporarily by accumulating a charge. Generally, film capacitors are designed to operate higher voltages, temperatures and frequencies than their ceramic counterparts. The MKP383268025JCA2B0 is one such film capacitor.

Applications

The MKP383268025JCA2B0 is designed to be used primarily in applications requiring high-voltage circuit protection and filtering, as well as energy storage. These include power supplies, motor drives, flow meters, guitar amplifiers, and similar applications. Its features such as its small size, high insulation resistance, and high current capacity make it especially well-suited for these applications.

Working Principle

The MKP383268025JCA2B0 works on the same principle as all other film capacitors. The two metal electrodes are separated by a dielectric, typically plastic film. When a voltage is applied to the capacitor, an electric field is created between the two plates, tending to create an accumulation of negative charges on one plate and positive charges on the other. This tendency for charge separation is opposed by whatever dielectric material is present between the two plates. As the amount of charge accumulates until it reaches saturation, an electrostatic field, in accordance with the laws of physics, will be created between the two plates. This electrostatic field modifies the electrical properties of the capacitor, enabling it to store electrical energy.

Construction

The MKP383268025JCA2B0 is a metallized polypropylene film capacitor constructed with two metal electrodes, a dielectric (generally polypropylene), a binder and a non-metallic end cap. The electrodes are formed by coating the dielectric with a thin layer of metal, typically aluminum. The binder is usually a polyester film and the end cap is usually a polyethyelene terephthalate (PET). This construction creates a capacitor that is designed to operate at a maximum voltage of 440 VDC, at temperatures between -55°C and +85°C, and has a maximum capacitance of 4.7 µF.

Performance Characteristics

The MKP383268025JCA2B0 is designed to provide very low loss, high insulation resistance and stability across a wide temperature range. In addition, this capacitor has a high rated voltage, and a high ripple current capacity. Inductance is kept to a minimum and the leakage current is very low.This combination of performance characteristics makes it a very versatile solution for a wide range of applications.

Conclusion

The MKP383268025JCA2B0 is a film capacitor, designed for applications requiring high-voltage protection, power filtering, and energy storage. Its small size and high stability across a wide temperature range make it well-suited for these applications. In addition, this capacitor has a high surge current capacity, low inductance and low leakage current, making it an ideal choice for a wide range of applications.
