Film Capacitors – B32656S8155K566 Application Field and Working Principle

Film capacitors have been widely used in different industries and fields due to their excellent electrical and mechanical properties, such as low loss, high insulation resistance and high surge voltage tolerance. The film capacitor (B32656S8155K566) is a film-based electrical component that consists of a dielectric layer of film, and multiple electrical plates that are wound on each other. This capacitor is most commonly used for AC/DC applications.

Capacitor Application Fields

Film capacitors can be used in a variety of different application fields. For instance, they are used for power factor correction, power supply filtering, and signal coupling. Other applications include signal transmission, transient suppression, wave shaping, and energy storage. The B32656S8155K566 is mainly used in applications where maximum power factor correction and current handling is required. It can also be used for motor start capacitors, AC/DC voltage converters and multiple motor control circuits.

Working Principle

Film capacitors work on a principle of accumulated charge transferring back and forth between the two plates created by a dielectric layer, as electric current runs through them. The dielectric layer of film separates the two electrical plates, similar to the way the dielectric in electrolytic capacitors separates its plates. Each plate has a potential difference, and when current runs through the capacitor, electrons are drawn to the plate with the higher potential. This causes an electric field to be created which is strong enough to overcome the dielectric layer resistance. As a result, the electrons accumulate on the plate with higher potential. This principle enables the film capacitor to store and release energy, as needed.

Performance and Characteristics

The B32656S8155K566 film capacitor has a capacitance rating of 815nF and a voltage rating of 250VAC. Its temperature range is between -40°C and +105°C, and it has a maximum dissipation factor of 0.83%. It also features a self-healing property, meaning that it can recover from minor short-circuits thanks to the dielectric\'s superior flexural strength. This capacitor also has excellent insulation characteristics, which makes it reliable for use in a variety of electrical equipment. The B32656S8155K566 film capacitor provides high reliability with great electrical, environmental and mechanical performance. This helps to decrease component losses and increase the life of the device, making it a great option for a wide range of applications. As such, it is an effective and reliable component for many different industries.
