Introduction

Film Capacitors, also called film dielectric capacitors, are type of capacitors composed of aluminum or tin foil with a thin plastic film. They are the most common type of capacitor and have been widely used in a variety of applications such as high voltage, power supplies, measuring devices, and many more. This article will focus on the specific model ‘QXK2E155JTP’ and discuss its application field and working principle.

Application Field

Film Capacitors, especially the ‘QXK2E155JTP’ model, are often used in high-voltage circuits in a wide range of applications due to their high voltage rating and low inductance. The ‘QXK2E155JTP’ has a nominal voltage rating of 2,500V, making it suitable for many applications. Examples include pulse or impulse circuits, high-voltage power supplies, power line connection protection circuits, and Power Factor Correction (PFC).

Working Principle

The working principle of the ‘QXK2E155JTP’ is the same as any other capacitor, in that it stores electric charge. However, the functioning of this specific model is slightly different due to its thin plastic film construction. The plastic film is usually a polypropylene or polyethylene which has a high dielectric constant and offers a higher efficiency than other capacitor types, such as electrolytic or tantalum capacitors. This design also leads to higher voltage ratings and lower inductance, making it ideal for high-voltage applications.

Design

The ‘QXK2E155JTP’ is a cylindrical-shaped capacitor with two metalized plastic films attached to each end. It has two terminals, the positive terminal on the right side of the capacitor and the negative terminal on the left side. It also has a plastic sleeve built around the capacitor to protect it from damage due to the high voltages it can be exposed to. The total capacitor size is 5mm x 20mm, making it suitable for use in small devices.

Conclusion

In conclusion, the ‘QXK2E155JTP’ is a type of film capacitor that is suitable for high-voltage circuits due to its high voltage rating and low inductance. It is a cylindrical-shaped capacitor with two metalized plastic films attached to each end and is designed for use in small devices. Its most common applications include pulse or impulse circuits, high-voltage power supplies, and Power Factor Correction (PFC). It is a highly efficient capacitor type and has many advantages over other capacitor types, such as electrolytic or tantalum capacitors.
