Introduction

Film capacitors, as one of the most important components in the electrical industry, play an indespensible role in many fields and applications. MKP1839415635 is one of the most popular and versatile film capacitors, widely used for various purposes, such as motor run, lighting, power supply, high frequency and audio. In this article, we will discuss the working principle and application field of the MKP1839415635 film capacitors, focusing on its advantages and disadvantages.

Working Principle

MKP1839415635 film capacitors are polar electrolytic capacitors, where the film is impregnated or coated with a thin layer of aluminum, which acts as the electrical connection between the electric current, and the capacitor elements. The connected film is then wound into a cylindrical winding, and electrodes are connected on either side.The MKP1839415635 film capacitors use the modern Three-Layer Film technique to fully utilize the capacitance of the elements. This technique involves winding three layers of film, each with different dielectric constants and performance characteristics. The outer layers are generally composed of Polyethylene Naphthalate (PEN), while the middle layer is made of Polyethylene terephthalate (PET). The middle layer has higher electrical resistance than the outer layers, creating a dielectric layer that can absorb more electric energy as well as have more capacitance.The PEN film on the outer layers of the MKP1839415635 film capacitors improve the capacitance by a significant amount when compared to a standard single-layer capacitor. The capacitance increases from 744pF/mm to 2214pF/mm by adding two layers of PEN. Furthermore, the dielectric strength, leakage current and voltage coefficient of the MKP1839415635 film capacitors are better than the single-layer capacitors.

Application Field

The MKP1839415635 film capacitors are used in a wide range of applications, from motor run, motor start, high-frequency and audio, to power supply, lighting, signal filtering, and many more.In motor run and motor start, MKP1839415635 film capacitors have the capability to absorb and store electric power, allowing motors to start and run more efficiently. Due to their dielectric strength, voltage coefficient and leakage current, these film capacitors are better equipped to handle the high voltage and continuously changing voltages of motor run applications.In audio applications, MKP1839415635 film capacitors are used to filter audio signals, rectify and amplify the signals, and provide frequency-change effects. These capacitors can improve the sound\'s clarity and response, resulting in richer and better-defined sound.Apart from these, MKP1839415635 film capacitors are also used as power supply in lighting and other industrial applications. With the help of these capacitors, power supply can be provided in a situation where power source is not available permanently or with insufficient energy. The film capacitors also provide a smooth and stable power source even when voltage fluctuates.

Advantages and Disadvantages

The most significant advantage of MKP1839415635 film capacitors is their ability to channel power more efficiently compared to single layer capacitors. The Three-Layer Film technique improves the capacitance per given volume, and allows for larger capacitance values per given size. This allows more electric energy to be stored in less space.In addition, MKP1839415635 film capacitors are extremely reliable and can hold their capacitance for long periods of time. They are also mechanically and thermally stable, and highly resistant to vibrations, moisture, and humidity.Despite these advantages, MKP1839415635 film capacitors are not without their disadvantages. One major downside is their high cost due to its complexity, and the fact that they need an individual winding machine to wind the film, which further increases the cost. Furthermore, they are relatively bulky and have a limited frequency range, which may be limiting for some applications.

Conclusion

In conclusion, MKP1839415635 film capacitors are widely used in various applications and fields, such as motor run, lighting, audio, and more. Their Three-Layer Film technique allows them to store more electric energy in less space. They are also highly reliable and resistant, making them an ideal choice for applications requiring long life and stability. However, they are relatively expensive and their limited frequency range may be limiting for some applications.
