Film Capacitors

Film capacitors are widely used in a variety of applications, due to their excellent performance characteristics, such as long lifetime, low equivalent series resistance (ESR), and low leakage current. Among these capacitors of this technology, the MKP1848622924Y2 is a popularly used type. This article introduces the application fields and working principle of the MKP1848622924Y2.

Application Field

The MKP1848622924Y2 is a metallized polypropylene capacitors with capacitor voltage of 250VAC (200VDC). It is specifically designed to provide the combined characteristics of long life and high reliability. Therefore, the MKP1848622924Y2 is widely used in applications such as high frequency switching converters, filters, power supplies, switching power supply filters, and other high frequency circuits.

In addition, since the MKP1848622924Y2 is a low loss type with good frequency characteristics, it is also applicable to audio line connection circuits, frequency discriminators, power amplifiers, auto volume circuits for televisions and other related applications.

Working Principle

The MKP1848622924Y2 capacitor is either a film-foil or metallized polypropylene capacitor. The layer of polypropylene film acts as the insulation component of the capacitor. On top of this layer, two metal electrodes are placed in contact with the film. The electrodes consist of either a layer of aluminium or other material, such as copper or silver.

The metallized part of the film capacitor is formed by condensing a thin aluminium layer onto the film. The current flows between the electrodes and the film through a crystal lattice that makes up the body inside the film.

The metalized metallized polypropylene film capacitors have good electrical characteristics in comparison to other types of film capacitors. They are particularly used in high frequency circuits because they have very low losses even at high frequencies, and they generate very little interference. In addition, they are also known for their low ESR and ESL (equivalent series inductance) which makes them very desirable in power supplies.

Conclusion

The MKP1848622924Y2 film capacitor is a commonly used type of film capacitor with a high level of performance. It is known for its long lifetime and high reliability. In addition, it has good electrical characteristics due to its low losses and low ESR. Therefore, the MKP1848622924Y2 film capacitor is widely used in various applications such as high frequency switching converters, filters, and power supplies.
