Film Capacitors

Film capacitors are polarized capacitors with a thin plastic film insulating layer. They are mainly used in applications which require stable, reliable and high performance in the fields of information, communication, DC power filtering, signal coupling, circuit decoupling, and power factor compensation. This article focuses on the BFC237944913 application field and working principle.

BFC237944913 Application Field

The BFC237944913 film capacitor’s ultra-wide bandwidth, low series inductance and low internal resistance offers superior performance in the most demanding applications. It is used in active circuits for data processing, in digital filters and for frequency-selective amplifying, high loss and broadband applications. The high-speed performance and low dielectric absorption contribute to these application fields.

In addition, BFC237944913 film capacitors are used in circuits which require high accuracy, stable operation over a wide temperature range and long life operation. BFC237944913 is a non-bonded type which is suitable for converting AC to DC (Rectifier Bridge PFC) for the measurement and control of AC/DC power supplies. The construction of this type of capacitor is especially suitable for high temperature applications up to 180°C without any significant performance degradation.

BFC237944913 Working Principle

BFC237944913 film capacitors are constructed of layers of thin polypropylene film dielectric material stacked together to form a flat capacitor body. The layers are separated by electrodes and insulated by a dielectric layer. The dielectric layer can either be a sheet of plastic, like polypropylene or terephthalate, or a tin foil coating. The metal electrodes are typically soldered onto the circuit board using a flux core solder.

The capacitor edges are sealed with epoxy resin to protect the interior from moisture. When voltage is applied to the capacitor, electrical charges accumulate on the plates, creating a small electric field between the plates. This results in a capacitance, which is the ability of the capacitor to store charge. This principle is the foundation of film capacitors, allowing them to function efficiently in a variety of applications.

Conclusion

In conclusion, BFC237944913 film capacitors are a reliable and efficient way to store electrical charge. They are used in applications which require stable, reliable and high performance due to their low series inductance and low internal resistance. They are also suitable for use in high temperature applications up to 180°C without any significant performance degradation. Film capacitors are built using layers of thin polypropylene film dielectric material and insulated by a dielectric layer. The working principle of these capacitors involves electrical charges accumulating on the plates, creating a small electric field between the plates, allowing them to store charge.
