Film Capacitors and their application field and working principle

Film capacitors are one of the most important components of electrical circuits. These specialized capacitors are available in different sizes, shapes and configurations and are used for a variety of purposes. In particular, film capacitors with the QXK2E155KTP model are often used for high power applications, as they are able to handle high current and voltage and produce a stable, reliable performance. Here, we take a look at their application field and working principle.Film capacitors are non-polarized capacitors, meaning that they can be connected either way between two points of a circuit. They are also known as polypropylene capacitors, which is because the material used to make them is polypropylene. This material is made up of alternating layers of polypropylene and the electrode layers, creating a compact structure with a large surface area. This structure is what allows the capacitor to store a large amount of energy.The QXK2E155KTP model of film capacitor is similar to other types of capacitors, but has slightly different specifications that make it suitable for high voltage and current applications. It is a multi-layer capacitor and has an insulation value of 4000V. It has high dielectric loss and is suitable for temperatures up to +125 degrees Celsius. It also has good tolerance, high Q and low ESR.The application field of the QXK2E155KTP model includes applications in high-voltage power supplies, LED displays, electrical appliances, and automotive systems. The capacitor is also suitable for audio equipment, and it is often used in car audio systems to provide clean, smooth sound reproduction. The capacitor is also commonly used in power factor correction and harmonic compensation applications.The working principle of the film capacitor can be explained as follows. The insulation layer between the internal structure of the capacitor prevents electric current from flowing between the layers, and only a very small amount of charge can pass through. When a voltage is applied to the capacitor, the internal layers become charged, which creates an electric field that stores the energy. As the charge is passed through the capacitor, the capacitor simultaneously discharges, restoring the electric field to its initial state. This process continues until all of the charges are equalized and the capacitor reaches equilibrium.Though film capacitors are less common than traditional electrolytic capacitors, their solid structure and ability to handle large amounts of current and voltage make them an excellent choice for certain high-power applications. The QXK2E155KTP model is an excellent example of this type of capacitor, with its high insulation value and stable performance. Its wide application field and relatively simple working principle make it an attractive choice for a variety of applications where reliability and high performance is a must.
