Film Capacitors

Film capacitors, also known as plastic film capacitors, polyester film capacitors, or mylar capacitors, use an incredibly thin polymer film as the dielectric material. This allows a capacitor to provide very unique performance characteristics (from various capacitance values to high ripple current ratings to low dissipation temperature coefficients). In addition, film capacitors are very reliable due to their electrical and structural stabilities - because of these attributes, or performance advantages, they are used in a wide range of applications and technology.

BFC247990089 Application Field and Working Principle

The BFC247990089 is a polypropylene film capacitor and is ideal for most high voltage applications, including industrial and automotive, due to its robust design and electrical characteristics. The BFC247990089 is equipped with a voltage rating of up to 1200VAC/DC, making it particularly suitable for filter, AC motor drive, and general purpose DC applications. The capacitor also features excellent temperature stability and low dissipation factor, making it highly reliable.

The BFC247990089 makes use of a metallic film as the dielectric material. An aluminium strip is placed within this dielectric material, and the combination serves as the electrodes for the capacitor. This means that when an AC voltage is applied across the capacitor, it charges up with both positive and negative charges. As the voltage changes, the current flowing through the capacitor also changes – this results in the two plates of the capacitor emitting electrons and ions. The alternating current generates an electric field within the capacitor, thus creating a ‘storing’ of energy which is discharged when the voltage is removed or changed.

Additional Advantages

The use of a metallic film as the dielectric material also has other advantages. For instance, it provides good frequency and voltage characteristics which make the capacitor suitable for power factor correction (PFC) circuits. The thin metallic film also allows for a higher capacitance per unit volume, as well as a smaller physical size than a traditional electrolytic capacitor. As the characteristics of film are reliable and stable over temperature.- this makes the BFC247990089 particularly resistant to high temperature and humidity.

The film capacitor has also become a popular option due to its cost-effectiveness. Compared to other types of capacitors, the cost of the film capacitor is substantially lower. This ensures that both manufacturers and consumers can benefit from their use in applications where cost savings are important.

Conclusion

The BFC247990089 film capacitor offers a wide range of advantages that make it an ideal choice for many high voltage applications. With its high voltage rating, excellent temperature stability and low dissipation factor, it provides superior performance in a range of applications. In addition, its use of a metallic film as the dielectric material allows for a higher capacitance per unit volume, as well as a smaller physical size than other types of capacitors, which makes the capacitor particularly cost-effective. As a result, the BFC247990089 is an excellent option for a variety of high voltage applications.
