BFC236966103

Film Capacitors

Film capacitors are electrostatic capacitors that use thin plastic films as the medium of insulation. These high-performance capacitors are available in both polarized and unpolarized versions, and come in a variety of shapes and sizes. They are preferred in many applications due to their greater efficiency and reliability compared to other types of capacitors. The BFC 236966103 is a large-capacity film capacitor, ideal for DC-DC applications.

Application Field

The BFC 236966103 film capacitor can be used in a wide range of applications. It is suitable for both low-voltage and high-voltage DC-DC converters, as well as power factor correction, power line filtration, inverters, and lighting ballast. It can also be used as a smoothing device, snubber, energy storage device, and voltage divider.

Working Principle

Film capacitors are made from a variety of materials, such as polypropylene, polyester, or polyethylene terephthalate (PET). These materials are typically layered together, and then the capacitor is formed by depositing electrodes on the surface of the plastic films. The capacitor\'s electrical field is defined by the surface area of the electrodes, and the distance between them, which is determined by the thickness of the plastic film. As a result, the BFC 236966103 provides high capacitance values with low leakage current, making it suitable for many DC-DC applications.

Film capacitors are usually preferred over other types of capacitors because they provide high capacitance without sacrificing volumetric efficiency. They are also very reliable, thanks to their ability to withstand voltage and temperature extremes. Additionally, they do not require any additional components, such as snubbers, to reduce their inductance or to increase their capacitance. As a result, they are very versatile and can be used in a wide range of applications, while still maintaining high performance.
