BFC2373GM474MF

Film capacitors are electronic components profoundly utilized in applications that require energy storage and constant voltage inputs. Perfect for power conditioning applications, the BFC2373GM474MF film capacitor is specifically designed for a wide range of applications, bringing excellent insulation capability, high reliability, and long life expectancy.

Components of the BFC2373GM474MF

The BFC2373GM474MF consists of two main parts: the film dielectric and the conductive electrodes. The film provides insulation between the two electrodes and determines the capacitance value. On the other hand, the conductive electrodes apply the voltage across the capacitor.

The dry-film and wet-film

The film is a polyester (PEN) composite designed to withstand high voltage and temperature extremes. Additionally, the film can be treated with a variety of treatments such as impregnation, anti-one treatment or wet-film deposition to improve its performance in different applications. Depending on treatment applied, we can differentiate between two films: the dry-film and the wet-film.

The Dry-film Capacitor

The dry-film capacitors are among the most advanced solutions available on the market. Featuring high dielectric strength, these capacitors are designed to offer minimum leakage current and provide enhanced stability. Additionally, the dry-film is the perfect choice when looking for a low temperature coefficient. Operating temperature ranges from -55°C up to +105°C (-67°F up to +221°F).

The Wet-film Capacitor

The wet-film capacitors offer more insulation resistance with an increased tolerable voltage. Operating temperature for these capacitors range from -55°C to +125°C (-67°F to +257°F). Additionally, these capacitors are designed to feature a higher capacitance value than their dry-film counterparts.

Working Principle

The working principle behind the BFC2373GM474MF film capacitor is very simple. When a voltage is applied, the electrons flow freely across the cloth-polyester film substrate of the capacitor. As this element has a specific capacitance, it builds up an electric field that resists the application of more voltage. This two-way action is the basis of how these capacitors work in different applications.

Conclusion

The BFC2373GM474MF is a high-performance film capacitor with exceptional features that make it a preferred choice for a variety of applications. Its components – the conductive electrodes and the film dielectric – are designed to meet the highest standards of quality, providing excellent insulation, stability and long life expectancy. Additionally, these capacitors offer a range of temperature coefficients, making them suitable for a wide range of applications.
