Film Capacitors

Film capacitors, also known as plastic capacitors, are constructed using two layers of a polymer-based material that are separated by an insulator layer, forming a dielectric between them. These layers are then insulated from each other by a layer of solid or liquid insulating material such as a gas.

Film capacitors are used in a wide variety of applications, such as power electronics, telecommunications, and audio systems, due to their high insulation resistance, low directly current (DC) and alternating current (AC) leakage, and low dielectric absorption. They can also be used for pre-stored energy applications, such as RF energy storage, lightning surge applications, and transient surge protection.

BFC247042273 Application Field and Working Principle

The BFC247042273 film capacitor is a high-voltage device with a voltage rating of 10kV and a capacitance of 2.7nF, making it suitable for use in applications such as electric energy storage, telecommunications, and lightning suppression. This film capacitor has a very wide frequency response, making it an ideal choice for applications such as high-fidelity audio systems.

The working principle of the BFC247042273 film capacitor is relatively simple. It uses an insulating material to create a dielectric layer between two thin metal layers, one of which is conductive and the other one is not. When an electrical voltage is applied across the capacitor, a current will flow through the conductive material, while the dielectric layer will prevent the electricity from passing through to the other metal layer. This creates a voltage drop across the underlying material, which is then stored as energy. This is how the capacitor works to store energy for use in whatever application it is used for.

The advantages of using the BFC247042273 film capacitors include its low self-capacitance, which is lower than other types of capacitors, such as aluminum and ceramic. This low value ensures high-speed response performance. Furthermore, the device also offers high surge and peak current handling capabilities. Additionally, the device features high thermal and electrical stability, long shelf life, and low risk of failure.

Overall, the BFC247042273 film capacitor is an ideal choice for use in applications such as electric energy storage, telecommunications, and lightning suppression, due to its high voltage rating, low self-capacitance, and high surge and peak current handling capabilities.
