Introduction

Film capacitors, also known as plastic film capacitors, are one type of electrostatic capacitor that uses a thin polymer film as the dielectric. The MKP1847H58031JP4, manufactured by Johnson Co., is one such capacitor. This robust component can be used in a wide variety of applications. In this article, the application field and working principle of the MKP1847H58031JP4 will be discussed.

Applications

The MKP1847H58031JP4 film capacitor is intended for use in a variety of applications. It can be used to store energy, as a charge stabilizer, or as a frequency-dependent filter for the suppression of ripple and interference. It is also well-suited for use in audio and signal processing systems, and as a snubber in power supplies. The MKP1847H58031JP4 is also highly suitable for use in automotive, industrial, and other rigorous applications. Its impressive temperature range, low ESR, and good tolerances ensure reliable operation even in the most demanding environments. Additionally, its small form factor allows for easy integration into existing designs.

Working Principle

At its core, the MKP1847H58031JP4 film capacitor works the same way as any other capacitor. It is composed of two metal plates separated by an insulating material, known as the dielectric. When a voltage is applied to the plates, an electric field forms in the dielectric. This electric field stores an electric charge on the plates. Thus, the MKP1847H58031JP4 works by storing electrical energy in the form of an electric charge.The MKP1847H58031JP4 is constructed from a polypropylene or polyester film as the dielectric material, and electrodes layered with an aluminium oxide coating. This combination of materials ensures reliable performance with excellent self-healing behaviour, while also allowing for very small physical dimensions. Additionally, the film provides superior temperature stability and low losses over the entire operating range.

Conclusion

In summary, the MKP1847H58031JP4 film capacitor is a robust and reliable component that can be used in a variety of applications. Its small size, excellent performance, and good tolerances make it ideal for use in automotive, industrial, and audio systems. The working principle of the capacitor revolves around the formation of an electric field between two metal plates separated by an insulating dielectric. The polypropylene or polyester film used in its construction provides superior temperature stability and low losses, while the aluminium oxide coating ensures reliable operation with excellent self-healing behaviour.
