Film Capacitors

Film capacitors are types of capacitors which use a film as the dielectric material rather than paper, mica, ceramic, electrolytic, or other types of dielectrics. This article will discuss the MKP1839447251 film capacitor’s application field and working principle.

Application Field

Film capacitors are commonly used in a wide variety of applications due to their small size, low cost, low equivalent series resistance (ESR), high reliability, and long service life. The MKP1839447251 film capacitor has a temperature range of -55 to +105°C and a rated voltage of 250V. It is often used in high-power amplifiers, in motor drive systems, in LED lighting systems, and in other high-voltage, high-temperature systems.

Working Principle

Film capacitors work based on the principles of electrostatics and dielectrics. When voltage is applied to a film capacitor, electric charges accumulate on each side of the dielectric material. This results in an electric field, and the accumulation of charge creates a potential difference between the two sides.The MKP1839447251 film capacitor has two metal plates, each with one surface covered in metal oxide film, separated by a polymer film dielectric. When a voltage is applied to the capacitor, the film dielectric experiences polarization due to the accumulated electric field. This results in a change in the electric field between the two metal plates, which creates a current. Therefore, the capacitor, in turn, stores electrical energy.The capacitor has a breakdown voltage of 350V. This means that the capacitor can safely handle a maximum voltage of 350V without causing any permanent damage.

Conclusion

The MKP1839447251 film capacitor is a reliable, cost-effective, and small size capacitor that is well-suited for a variety of applications, such as high-voltage and high-temperature systems. It works on the principles of electrostatics, dielectrics, and polarization and is capable of storing electrical energy. It has a breakdown voltage of 350V which makes it suitable for high voltage systems.
