Film Capacitors

Distinctly different from ceramic capacitors, film capacitors are an important part of many electronic systems. Modeled after their ceramic counterparts, film capacitors use thin layers of plastic or similar dielectric material to hold charge, while ceramic capacitors use a dielectric ceramic material. The type of dielectric material used determines the efficacy of the model. Film capacitors come in a wide variety of models and can provide better performance in certain applications. With the help of a BFC2370FE123 model film capacitor, a working understanding of this type of application can be achieved.

BFC2370FE123 Application Field and Working Principle

The BFC2370FE123 model film capacitor is a highly versatile, polyester film capacitor that has a wide range of applications. Its high electrical and dielectric strength, along with its long-term stability, makes it fit for automotive, military, and special-purpose, audio applications. Due to its superior performance in varied conditions, it is also ideal for use in harmonic and surge suppressors, DC-link capacitors, high-voltage control, decoupling and filtering.

To understand the working principle of the BFC2370FE123, it’s important to first look at the construction. This type of film capacitor consists of a polyethylene terephthalate (PET) film, a small piece of aluminum foil, and electrodes that are both etched onto the PET film. The two metals of the electrode are separated and insulated by the film. As an electric current is applied to the capacitor, the electrode layers become charged, inducing an electric field between them. This electric field creates an electrostatic charge that is stored between the two electrodes. In other words, the capacitor works as an electrical energy storage device.

Conclusion

The BFC2370FE123 model film capacitor is ideal for many applications, due to its high electrical and dielectric strength, long-term stability, and high-recharge capability. Its wide-range of available sizes and configurations, makes it highly adaptable for use in automotive, military, and special-purpose audio applications. A comprehensive understanding of the fundamental working principle of a film capacitor such as the BFC2370FE123, is essential for the proper functioning and maintenance of any such device.
