Film Capacitors

Film capacitors, also known as plastic film capacitors or film dielectric capacitors, are capacitors which use a thin plastic film as the dielectric. They are used mainly for applications with higher stability or lower product size compared to conventional ceramic capacitors. Film capacitors are generally current-limited, low-voltage components. This means that the total energy available from a film capacitor is much smaller compared to a ceramic capacitor of the same size.

BFC2370CI124 Application Field and Working Principle

The BFC2370CI124 is a general purpose film capacitor designed for use in power supply/voltage filter applications, such as medical/audio/video equipment, DC/DC converters, UPS systems, and power amplifiers. It offers a wide frequency range of up to 25kHz, extended surge capability, good insulation resistance and a high dielectric strength. It offers excellent frequency and temperature stability and low EMI noise. The capacitance tolerance of this model is also lower than other film capacitors.

The BFC2370CI124 is a two terminal, self-healing film capacitor with electrolytic tin/lead finish. It works on a basic principle of charge storage, where two connected electrodes that are separated by a dielectric material (in this case a film) store an electric charge. When the capacitor is energized, a current will flow from one electrode to the other, and electric charges will be stored in the dielectric material. This stored charge is known as the capacitance, and it is measured in Farads. The larger the capacitance, the greater the amount of electric charge that can be stored.

The BFC2370CI124 is designed to have a higher capacitance than other film capacitors. This is due to its multi-layer construction, which allows multiple overlapping dielectric sleeves. This means that more charge can be stored in a smaller form factor. Additionally, the fourth layer adds further stability and capacitance over temperature. This means that the operating temperature range of the BFC2370CI124 is wider than other film capacitor models.

In terms of working performance, the BFC2370CI124 has a working voltage range of 1.25 to 400VAC, and an insulation resistance of 1 GΩ. Additionally, it has an ambient humidity of 85% and a operating temperature range of -40°c to +105°c. The BFC2370CI124 is also RoHS compliant and UL/CSA approved, which makes it suitable for applications where safety and reliability are paramount.

In conclusion, the BFC2370CI124 is a general purpose, two terminal film capacitor which is designed for power supply/voltage filter applications. It has a large capacitance and a low temperature drift, allowing for stable performance over a wide range of temperatures. Additionally, it has a high dielectric strength and good insulation resistance. It is also RoHS compliant and UL/CSA approved.
