Film capacitors are a type of capacitor that uses a thin plastic insulator layer to separate two metal plates. The BFC2373GM105MI is a film capacitor specifically designed for energy-saving LED lighting applications, where it can provide excellent electrical performance and quality. This article will discuss the application field and working principle of the BFC2373GM105MI in greater detail.

Applications of the BFC2373GM105MI

The BFC2373GM105MI is designed to be used in medium voltage, high current LED lighting applications, such as street lighting, floodlighting, and directional lighting. Its low ESR and high current capability make it suitable for dimming applications, and its high ripple current rating makes it suitable for high power applications as well. In addition, its surge peak voltage rating is up to 6kV, which is ideal for applications that are exposed to surges and lightning strikes.

The BFC2373GM105MI also has excellent insulation performance and a high breakdown voltage rating of up to 4kV (dielectric strength). This makes it suitable for high current applications where insulation performance is critical.

In terms of physical design, the BFC2373GM105MI features a self-healing plastic film insulation layer that helps prevent short circuit failures. This feature also makes the capacitor suitable for long-term use in vibrating or shock-prone environments.

Working principle of the BFC2373GM105MI

The BFC2373GM105MI is a film capacitor whose working principle is based on electric field formation. It consists of two metal plates, separated by a thin insulating film. When DC voltage is applied to the two plates, an electric field is created between them, causing the electrons on the plates to move in opposite directions. This creates an electrical charge on the plates, which in turn produces a capacitive effect.

The capacitive effect of the BFC2373GM105MI is determined by its capacitance value, which can range from 0.1uF to 47uF. The capacitance value depends on the plate area, distance between the two plates, and thickness of the insulating film. As the voltage applied to the plates increases, the capacitance decreases because the electric field created between the plates is weaker.

The BFC2373GM105MI is also able to resist surges and lightning strikes due to its high surge peak voltage rating of up to 6kV. This is because the electric field between the plates is strong enough to dissipate the energy of the surge or lightning strike without causing the capacitor to break down.

Conclusion

The BFC2373GM105MI is a film capacitor specifically designed for LED lighting applications. Its low ESR and high current handling capability make it suitable for dimming applications, while its high ripple current rating makes it suitable for high power applications. Furthermore, its self-healing plastic film insulation layer and high breakdown voltage rating of up to 4kV make it suitable for high current applications where insulation performance is critical. Finally, its high surge peak voltage rating of up to 6kV allows it to resist surges and lightning strikes. This concludes our discussion on the application field and working principle of the BFC2373GM105MI.
