Film Capacitors

Film capacitors are type of electronic components which have the capacity to store electric energy as an electric field. This kind of capacitor generally consists of two parallel conductive surfaces separated by a dielectric material which can be made from a variety of materials such as plastic films, paper, or liquid. They have a wide range of applications, from signal filtering to voltage smoothing and decoupling in electronic and electrical circuits at both low and high frequencies.

The B81130C1104M is a specific type of film capacitor suited to a wide range of applications. It is a 4.7 µF/100 VAC capacitance value and has a rated operating temperature of -40 degrees Celsius to +85 degrees Celsius. The materials used for its construction are polypropylene film dielectric, components with screw-fits, and copper foils. It also has a 5 mm pitch, and is 14.3 mm long by 8.5 mm wide.

Applications of B81130C1104M

The B81130C1104M is a high-performance capacitor which is well suited to many applications including those in home audio and car audio systems, digital power supplies, electric motor circuits, industrial control devices, switching power supplies, and electronic consumer products. It is also suitable for general purpose power supplies and motor starters.

Working Principle of B81130C1104M

The working principle of the B81130C1104M is based on the same principles as other film capacitors. The two conductive surfaces of the capacitor are separated by a dielectric material (in this case, a sheet of plastic film). When a voltage is applied between the two surfaces, an electric field is created, allowing electric charge to accumulate on the conductive surfaces. This creates a potential difference between the two surfaces, allowing current to flow between them.

The plastic films used for the B81130C1104M have a very low dielectric loss, meaning that the capacitor can store the electric charge for a longer period of time compared to other types of capacitors. This makes them ideal for applications such as electronic filters, smoothing out DC power supplies to reduce noise, and decoupling circuits to reduce power supply ripple.

Conclusion

The B81130C1104M is a high-performance film capacitor which is well suited to many applications. Its plastic film dielectric allows for a very low electrical loss, making it suitable for a variety of applications including audio systems, digital power supplies, electric motor circuits, industrial control devices, switching power supplies, and electronic consumer products.
