Film capacitors, also known as plastic film capacitors, are made of multiple micron-level thin films, which have a large plastic area and are wound with appropriate capacitance. The BFC233812154 application field and working principle of film capacitor are introduced in this article. Application FieldFilm capacitors are widely used in low- and medium-voltage power systems due to their high withstand voltage, small size, light weight, high rated current and small temperature coefficient. It is suitable for gain-adjustable circuits with medium frequency and high gain in electronic televisions and monitors, amplifying circuits of communication equipment, switching power supplies and three-phase four-wire neutral systems, as well-as the high-frequency oscillation circuits of computers.Film capacitors are the main types of capacitors used in power electronic conversion due to their superior high-temperature resistance and higher withstanding voltage as compared to other types of capacitors. Thus, they are ideal for use in power supply circuits, such as converting AC from mains voltage to DC voltage with a capacitor as a filter, or for operation of DC to AC inverters.Working PrincipleFilm capacitors are capacitors that use thin layers of materials such as plastic, paper, or mica as a dielectric material instead of air or ceramic. This type of capacitor works by creating a static electric field that acts like a barrier between two conducting surfaces, which are usually composed of metal plates. The area between the metal plates is filled with an insulating material that has a dielectric constant greater than one. The dielectric constant is a measure of how much electrical potential the material can withstand.When the metal plates are placed in contact with a voltage source, current will flow through the capacitor. This current flow creates an electric field within the insulating material and produces an energy storage effect. The amount of energy stored is proportional to the voltage, the dielectric constant of the insulation material, and the size of the capacitor.ConclusionThe BFC233812154 application field and working principle of film capacitors explain how they are used in a variety of applications, including power electronic conversion and other low- and medium-voltage power systems. They feature high withstanding voltage and excellent temperature stability, making them an ideal choice in a wide variety of applications. Film capacitors are also relatively easy to manufacture and are relatively inexpensive, making them a cost-effective choice for many applications.
