Film Capacitors

Film capacitors, also known as plastic film capacitors, comprise a thin, self-healing dielectric material to be stacked between two conductive electrodes. This creates a parallel plate arrangement which provides effective electrical insulation and capacitance. The BFC237322126 model of film capacitor is designed for signal filtering applications such as audio equipment and radio-frequency interference (RFI) reduction. Additionally, it is suitable for pulse and power conditioning in power supplies and motor control.

Application Field

The BFC237322126 film capacitor is a voltage-dependent capacitor used in power electronic integrated circuits that require robustness and reliability. Its low capacitance combined with high voltage ratings and temperature-stable dielectric provide users with a capacitor that can efficiently control the sudden surge of electric current and voltage that inevitably occurs when electric devices are switched at high frequencies. While the capacitor is typically used in consumer electronic applicatis, it also has applications in the automotive, medical, and military industries.

Working Principle

When a voltage is applied to the BFC237322126 film capacitor, it produces a field force to polarise the dielectric material, making it a type of polarised capacitor. The thin dielectric material between the two films allows for a high capacitance in a small volume of space. As the capacitor is charge-dependent, it is able to not only store electric energy, but also to convert between charge and voltage. This makes the film capacitor an effective device for filtering and regulating high frequency signals in power systems, in which large pulses or transients in voltage and current can occur.

Conclusion

The BFC237322126 film capacitor is a bipolar device used for a variety of signal filtering applications in the consumer electronics, automotive, medical, and military industries. Its low capacitance ratings, robust construction and temperature-stable dielectric make it the perfect choice for high frequency, charge-dependent applications.
