Film Capacitors

Film capacitors, also referred to as foil capacitors, are a type of electrostatic capacitor. They are constructed with thin film dielectric layers and multiple metal electrodes. Compared to other capacitor types, such as ceramic and paper capacitors, film capacitors are relatively large in terms of physical size but offer the advantages of high insulation resistance, good temperature stability and excellent frequency characteristics. The type of film capacitor used for most applications is polycarbonate film, which provides UL 1446 recognition.

BFC236717474 Application Field and Working Principle

The BFC236717474 film capacitor is suitable for use in a wide range of applications thanks to its many valuable features. Commonly used for power supply, high frequency and impulse current circuits, these capacitors also work well in electronic equipment, fuse switchgear and lighting equipment. In addition, the components are extremely resistant to vibrations, temperature fluctuations and high humidity. As such, they are often used in automobiles, audio systems and HID lamps.

A film capacitor operates and works differently than most capacitors. Instead of storing energy by accumulation of charge on parallel metal plates, a film capacitor stores energy by accumulating electrical charge in thin layers of film. The two layers of film act as the two plates of a capacitor while the insulation between them acts as the dielectric. The layers of film are separated by conductive electrodes which form the contacts for the energy to flow. The spacer between the two layers of film creates a uniform charge distribution. This means that the capacitors can even handle very small voltages.

The advantages of the BFC236717474 Film Capacitor come from its unique construction. The film layers are securely held in place by two metallic plates which are insulated from each other. This creates reliable insulation between the positive and negative capacitance, resulting in a stable working voltage, low impedance and excellent energy storage. Furthermore, the film layers can withstand high temperature and are suitable for a wide range of working environments. And because the capacitors have high insulation resistance and do not biodegrade, they are extremely reliable and last for long periods of time.

The performance of a BFC236717474 film capacitor is consistent and dependable. Its capacitance value remains stable even with substantial fluctuations in temperature or after long periods of use. Furthermore, their low equivalent series resistance (ESR) and low dissipation factor (DF) make them ideal for high frequency applications. As such, they are often found in audio, radio and automotive applications.

In conclusion, the BFC236717474 film capacitor is an excellent choice for a wide variety of applications. Its reliability and consistency make it ideal for audio, automotive, power supply, high frequency and impulse current circuits. Its high insulation resistance, low impedance and excellent energy storage further make it ideal for a plethora of applications. As such, it is the go-to choice for many products needing reliable and long-lasting capacitors.
