Film capacitors, or film dielectric capacitors, are a type of capacitor that utilize a polymer film as a dielectric. The B25620B118K882 is a film capacitor designed for high-voltage, high power applications. This article will discuss the application field and working principle of the B25620B118K882.
Application Field
The B25620B118K882 is designed for high-voltage, high power applications. This makes it suitable for power electronics, such as inverters, motor drives, and welding equipment, which often require high voltage and power capability. Additionally, the B25620B118K882 is resistant to electrical breakdown at high voltages, further making it suitable for such applications.
Working Principle
At its most basic level, a film capacitor functions by storing electrical energy, similar to an ordinary capacitor. A film capacitor is made up of two electrical conductors separated by a dielectric material, which in this case is a polymer film. The polymer film is highly resistant to electrical breakdown under high voltages, making it ideal for high-voltage applications.
When voltage is applied across the two conductors, electrical charge will accumulate on the conductor surfaces. The amount of charge stored on the conductor surfaces is limited by the size of the capacitor and the dielectric material used. This is known as capacitance, and it is measured in Farads.
The B25620B118K882 is a high-voltage film capacitor with a capacitance of 500V. This makes it suitable for high-voltage applications, such as those mentioned above. Additionally, the B25620B118K882 has a low equivalent series resistance, meaning that it is able to more effectively convert energy back and forth from the power source without heat or voltage loss.
