Film Capacitors – BFC236612394 Application Field and Working Principle

Introduction

Film capacitors, also known as film dielectric capacitors, are passive components of electrical capacitors with a polyethylene or polypropylene film dielectric and two electrodes. The capacitance, which depends on the dielectric constant of the film and the overlapping area of the electrodes, is relatively low compared to other types of capacitors, but film capacitors have a wide frequency range, low temperature coefficients and superb properties in terms of operation stability, steadiness and electrical reliability. This article will focus on one of the film capacitors, BFC236612394, and discuss its application field and working principle.

Application Field of BFC236612394

BFC236612394 possesses excellent electrical properties, reliability and operating stability, making it suitable for use in high-reliability systems such as military and aerospace. It is often employed in the output filters of power supplies, audio/video equipment and switching power supplies, and also in the filters of digital circuits. Moreover, BFC236612394 can be used as an AC discharget circuit protector against AC leakage in TVs, VCRs, air conditioners and refrigerators.

Working Principle

A film capacitor basically consists of a thin film of dielectric material sandwiched between two metal electrodes. The dielectric of the capacitor prevents the current from flowing through the capacitor; instead, it stored electric charge in the capacitor.The BFC236612394 has a polypropylene film dielectric and two electrodes. The voltage applied between the two electrodes, combined with the dielectric strength of the film, creates an electric field in which current can flow through the capacitor. The capacitance of the BFC236612394 is determined by the dielectric constant of the film and the overlapping area of the electrodes, and its capacitance is relatively low in comparison to other types of capacitors.When alternating current is applied, the BFC236612394 acts as a low-pass filter, allowing the passage of low frequency signals while attenuating the high frequency ones; and it also functions as an active component in rectifying circuits, reducing the rate of voltage fluctuations.

Conclusion

In summary, the BFC236612394 film capacitor is often used in high-reliability systems due to its excellent electrical properties, reliability and stability. Its capacitance is determined by the dielectric constant of the film and the overlapping area of the electrodes, and it functions as a low-pass filter and active component in rectifying circuits. The BFC236612394 film capacitor is indeed a valuable and reliable component in many industry applications.
