Film Capacitors: MKP1847H56031KP4 application field and working principle

Film capacitors, also known as metallized polypropylene film capacitors, are one type of metallized capacitors that have become increasingly popular in consumer applications over the past few years, due to the improved performance and lower cost compared to the more traditional disc capacitor technologies.

The MKP1847H56031KP4 is a type of film capacitor with a voltage rating of 400V, and a capacitance value of 0.047µF. It is a metallized polypropylene film capacitor with metallized electrodes and self-healing properties. It has a long life of more than 30000 hours.

The main benefit of film capacitors is that they are non-polarized and have a higher volumetric efficiency than electrolytic capacitors. They are also free of electrolytic degradation, which happens to electrolytic capacitors over time due to the chemical breakdown of their electrolyte. This can lead to performance degradation or even complete capacitor failure.

Film capacitors also have a lower parasitic inductance than electrolytic capacitors, making them ideal for high frequency applications, such as in laptops, mobile phones, and other consumer electronics. Furthermore, MKP1847H56031KP4 capacitors have excellent temperature stability and voltage stability. This makes them suitable for use in high-temperature environments, such as in car engines and in solar panel inverters.

The working principle of the MKP1847H56031KP4 capacitor is based on the fact that two metalized plastic foils are separated by a thin plastic film, and electrical energy is stored as the electric charge of the metalized surface accumulates. The capacitance of the MKP1847H56031KP4 capacitor is determined by the distance between the two foils and the surface area of the two metallic layers. With successive increases in voltage, the stored charge increases steadily until it reaches a certain maximum. When the maximum charge is reached, the capacitor is said to be "saturated".

In terms of applications, the MKP1847H56031KP4 capacitor can be used for a variety of applications, ranging from filtering to energy storage, power factor correction, and noise reduction. This type of capacitor is typically used in power supplies, industry inverters, high-voltage systems, and audio applications. The MKP1847H56031KP4 also has both short circuit and overvoltage protection, and is therefore ideal for use in DC/DC converters, motor drives, and AC/DC converters.

To summarize, the MKP1847H56031KP4 is a type of film capacitor with a voltage rating of 400V and capacitance of 0.047µF. It is non-polarized and has a higher volumetric efficiency than electrolytic capacitors. It also has a lower parasitic inductance and excellent temperature and voltage stability, making it ideal for use in a range of high temperature applications. Furthermore, its working principle is based on the fact that two metalized plastic foils are separated by a thin plastic film, and electrical energy is stored as the electric charge of the metalized surface accumulates. This capacitor is typically used in power supplies, industry inverters, high-voltage systems, and audio applications.
