BFC237139474

Film capacitors, along with their other varieties, are some of the most common forms of energy storage and frequency tuning components commonly used in all sorts of electronic circuits. Among them, the BFC237139474 is a uniquely constructed capacitor that is specifically designed for precision-tuned applications. In this article, we will take a closer look at the application field and working principle of this specific film capacitor.

What is a Film Capacitor?

A film capacitor (or film dielectric capacitor) is an electrical component typically made of film (PVC, polyester, polycarbonate, polypropylene or polyethylene terephthalate, Filmfoil, and so on) as the dielectric. The film is typically applied as a thin film of plastic or paper coated with metal to create a surface conductivity. Such capacitors are formed by winding two identical thin films with metal layers in opposite directions which can be interconnected in series to increase the total capacitance. This form of construction helps to create an even more efficient dielectric between the two layers and at an extremely low equivalent series resistance (ESR), which is an extremely beneficial characteristic.

BFC237139474 Application and Working

The BFC237139474 is a highly precise capacitance value, polycarbonate-film capacitor that is great for applications requiring highly precise values. It is specially designed to provide stable capacitance values, even in extreme temperatures, due to its unique construction and extended stability range. It also has a low equivalent series resistance (ESR) and excellent self-healing ability. As such, it is very suitable for use in power converters/inverters and other frequency-controlled devices.

The working principle of the BFC237139474 is based on the factor that two conductive plates of opposite polarity and equal area, separated by an insulating dielectric, form an electric field between them. Thus, when a certain voltage is applied across the two plates, the electric field causes the electrical charges to separate and store energy as an electric field. The charge stored in this electric field is known as the capacitance. Therefore, a capacitor stores energy by changing the separation of electric charges in an electric field.

The BFC237139474 is designed to provide superior performance and excellent quality in all operating conditions and temperatures. It offers excellent tolerance, low ESL (equivalent series inductance), low ESR (equivalent series resistance), low current leaks, and self-healing ability. As such, it is ideal for use in precision-tuned circuitry such as power supplies, AC/DC converters, low-noise circuit, PWM motor speed control, etc.

Conclusion

The BFC237139474 is a uniquely constructed film capacitor that is designed for precision-tuned applications. It offers exceptional stability, low ESR, and low ESL performance due to its impressive build. Moreover, it also has an exceptional self-healing ability which makes it an ideal choice for use in power converters and other frequency-controlled devices.
