Film Capacitors

Film capacitors, also known as polymer film capacitors, are electrical components that use thin plastic films, such as polypropylene, as the dielectric material between two electric conductors. They are suitable for applications with high frequency, high voltage, high current, and high vibration. A film capacitor is one of the most reliable capacitor types available. The BFC241901803 is a high quality product of this range.

Applications for BFC241901803

BFC241901803 is a heavy film capacitor used in various high-voltage applications, such as:

• High voltage switching power supply, UPS, and welding machine
• High voltage LED lighting
• High voltage motors or appliances
• Radio frequency and high frequency
• High voltage automatic control system

Working Principle of BFC241901803

BFC241901803 is constructed with a flexible plastic film that is plasticized with epoxy resin. That film is the dielectric element separating two layers of copper terminal plates. This structure allows the capacitor to exhibit excellent electrical performance with low loss, high insulation resistance and stable capacitance in the long term.

The operating principle of a film capacitor is based on a very thin dielectric layer between metal foil. When voltage is applied to the electrodes forming an electric field, charge carriers are attracted and stored on the two sides of the dielectric layer and the capacitor will be charged. This capacitor can be discharged when a reverse voltage is applied.

Advantages of BFC241901803

BFC241901803 provides several advantages over other types of capacitors:

• Stable operation due to the unique combination of insulating material and metal foil
• High tolerance to high temperature, high vibration, and shock
• Excellent electrical performance
• High insulation resistance
• Low equivalent series resistance (ESR), resulting in low insertion loss and excellent frequency response
• High peak voltage capability

Disadvantages of BFC241901803

The disadvantages of using BFC241901803 include:

• High cost due to the intricate fabrication process
• High sensitivity to moisture
• High leakage current

Conclusion

BFC241901803 is an excellent product from the film capacitor range. Thanks to their unique construction, film capacitors have a wide range of applications in a vast array of industries. They have excellent electrical performance and high tolerance to high voltage, high temperatures, and vibrations. Although these capacitors are expensive, they have many advantages. However, they are sensitive to moisture and have a high leakage current.
