Film Capacitors

BFC237228684 Application Field and Working Principle

Film capacitors are one of the most reliable and common types of capacitors, largely due to their excellent characteristics. The BFC237228684 are a type of film capacitors, and they offer a variety of unique benefits. The following article will discuss the application field and working principle of the BFC237228684.

Application Field

BFC237228684 film capacitors have primarily been used in areas that require high-quality, high-reliability, and extreme long-term stability of capacitance and dissipation factor characteristics. Common application fields for them include automotive electronics, communications systems, solar panel systems, and busway systems. They have also found use in audio systems, radio communications, and other high-precision electrical equipment. These capacitors are usually used when larger capacitance values are necessary.

Working Principle

The BFC237228684 film capacitors are made of multiple layers of metallized polyester film. The main part of the capacitor is an internal dielectric which is winding around by three 1.6mm thick layers of compacted metallized polyester film. This metalized film is then wound into a coil and sealed with epoxy resin in order to protect it. By adding a small amount of impregnating oil, the capacitor is able to maintain a high capacitance and heat resistance.

The capacitor is also equipped with a built-in safety device called a “high-dissipation” fusible resistor. This resistor is capable of detecting and limiting any overloads that are placed on the capacitor. If an overload is detected, the resistor will reduce the voltage across the capacitor, while simultaneously preventing high currents from flowing through the capacitor. This feature makes the BFC237228684 film capacitor one of the most reliable and safe capacitors available.

Conclusion

The BFC237228684 film capacitors are a reliable, accurate, and safe solution for any applications that require the highest levels of precision and stability. Their remarkable characteristics and built-in safety features make them an ideal choice for a variety of applications. Whether it be a solar panel system or a high-frequency radio communication system, the BFC237228684 are always up to the task.
