Film Capacitors

BFC247990181 application field and working principle

Film capacitors, sometimes called plastic film capacitors, are a type of capacitor in which the dielectric is a thin plastic film. Usually, this plastic film is wound into a cylindrical shape. Film capacitors have a high maximum voltage rating, up to several thousand volts. This makes them suitable for many types of high-voltage applications. Additionally, their dielectric medium has a high dielectric constant. This makes them desirable for many kinds of circuit applications.

Application Field

BFC247990181 film capacitor is designed for use in HVAC/R applications, such as defrost, heat pumps, pool heaters, and air conditioners. BFC247990181 offers excellent thermal stability, high dielectric strength, low ESR, and high capacitance values. This makes BFC247990181 ideal for use in electronic circuits and HVAC/R applications. The capacitor is available in a variety of capacitance values, with voltage ratings ranging from 10 mF to 2 uF.

Working Principle

BFC247990181 utilizes a polypropylene plastic film as its dielectric medium. The film is typically coated with an oxide in order to increase the breakdown voltage between the capacitor plates. This oxide coating minimizes leakage current, increasing the capacitor\'s capacitance over time. When an AC signal is applied to the plates of the BFC247990181 capacitor, electric current is drawn through the capacitor. The current is then stored and will remain stored until the AC signal is removed or the capacitor is discharged.

Conclusion

BFC247990181 film capacitors are ideal for use in HVAC/R applications, due to their high maximum voltage rating and their superior dielectric constant. Additionally, the capacitor\'s plastic film construction ensures excellent thermal stability, low ESR, and long-term reliability. Therefore, the BFC247990181 is an excellent choice for any HVAC/R application.
