Film capacitors, also known as plastic film capacitors, are passive components that store electrical energy in the form of electric charge. Compared to other types of capacitors (such as electrolytic capacitors and ceramic capacitors), film capacitors have a low equivalent series resistance (ESR), better frequency and temperature characteristics, and excellent insulation properties. As a result, film capacitors are widely used in power supplies, signal circuits, signal transmission lines, amplifiers, televisions, surface mount devices, and many other electronic applications.

MKT1820622065 film capacitor is a very high-performance self-healing type safety capacitor with a cylindrical housing and 19mm diameter and 62mm length. It is perfect for applications in high frequency systems, such as Schneider Electric\'s intelligent lighting and data analysis systems. These capacitors are designed to have low inductance characteristics and excellent dielectric properties to increase performance and reliability.

Application Fields of MKT1820622065

MKT1820622065 film capacitors are widely used in various electrical systems such as power conversion, audio equipment, switching power supplies, solar inverters, high-frequency power supplies, high-frequency rectifiers, and various filters. Some of the advantages that make them suitable for these applications include their high frequency transmission, small size, low inductance, and low ESR.

They have excellent frequency characteristics, making them suitable for high- frequency filters, attenuation of high-frequency signals or other signal transmission functions. Besides, they are perfect for pulse current modulation applications and in AC and DC electric drives due to their small dimensions and low inductance.

Working Principle

The working principle of MKT1820622065 film capacitors is based on the principles of capacitance and dielectric strength. The capacitor consists of two metal plates that are separated by an insulating material called a dielectric. When a voltage is applied to the capacitor, the electric field generated acts on the dielectric, causing it to become polarised by electrons moving in its structure. This causes a charge to be stored on the plates that is proportional to the voltage applied. This stored charge can then be used to supply current when needed.

The dielectric used in MKT1820622065 capacitors is polyethylene film which is vapour deposited with a thin metal layer. This gives the capacitor excellent temperature, humidity and voltage characteristics, as well as very high insulation resistance. The capacitors also benefit from excellent high frequency characteristics, high capacitance stability and very low ESR, making them an excellent choice for high frequency applications.

Due to their excellent electrical properties and reliability, MKT1820622065 film capacitors are used in a variety of applications. They are ideal for electronic and electrical applications where high frequency and temperature operation is required, as well as in filters, oscillatory circuits, and energy storage applications where self-healing is critical.

Conclusion

In conclusion, MKT1820622065 film capacitors are an excellent choice for a variety of electronic applications due to its excellent electrical properties and its ability to self-heal. They are capable of operating in high frequency and temperature applications, and come with a very low ESR due to their polyethylene-based dielectric structure. As a result, they are widely used in power supplies, signal circuits, signal transmission lines, amplifiers, televisions, and surface mount devices.
