Film Capacitors

Film capacitors, also known as plastic film capacitors, are electrical components that are mainly constructed using polymers films like polypropylene or polyester as the dielectric, and typically have three terminals. These capacitors are widely used in industries for high-frequency AC and pulse current applications, due to their low losses and high-temperature stability. On account of their reliability under harsh operating conditions, film capacitors are often used in electric cars and as replacements for electrolytic capacitors.

BFC242018202 Application Field and Working Principle

The BFC242018202 is a polypropylene film capacitor that is suitable for use in a wide range of AC and DC applications. It is a Class X2 capacitor, meaning it is designed for applications where high voltage and high frequency are expected. This capacitor has an Aluminized Polypropylene dielectric and has a voltage rating of 2.5kVAC and a capacitance of 20uF. The BFC242018202 is highly stable due to its robust construction, and it is able to withstand temperatures of up to 125 degrees Celsius.

The working principle of a film capacitor is based on the same principle as any other type of capacitor. A capacitance is created by forming two conducting plates of opposite charge and then separating them with an insulating material. The voltage applied between these plates creates an electric field, which in turn produces a charge storage. The greater the amount of charge stored, the greater capacitance of the capacitor. The dielectric material used in a film capacitor is typically a thin plastic film, which is why they are also known as plastic film capacitors.

The BFC242018202 is widely used in power supplies, lighting systems, and motors, as well as in high-frequency and electronic circuits. It can also be used in radiation-tested applications such as medical equipment, aviation, communications, and military systems. Its robust construction and reliable performance make it a popular choice for many applications.

In conclusion, the BFC242018202 is a robust and reliable film capacitor that is well-suited for a variety of high-frequency, high-voltage applications. Its Aluminized Polypropylene dielectric material makes it highly stable and able to withstand temperatures up to 125 degrees Celsius. Its performance and stability make it a popular choice for a range of industries, including power supplies, motors, electronic circuits, and medical equipment.
