Working Principle

After being introduced in the early 1960s, film capacitors have become an important part of modern electronics. Film capacitors are constructed of rolled up sheets of special plastic films (such as polyethylene terephthalate or polypropylene film) which are separated by insulating oil. The two metal layers, which are usually copper or aluminum, serve as the capacitor’s plates. This structure is then laminated with a thermoset epoxy. The result is a capacitor that has high capacitance, low leakage current, and excellent stability and reliability. The BFC237511302 is an example of this type of film capacitor.

Film capacitors work by storing energy in an electric field. When voltage is applied across the plates, an electric field is generated between the plates. This electric field eventually builds up and carries current when discharged into an external circuit. The energy stored in the electric field is then released, producing a current. The advantage of film capacitors compared with other capacitor types is that they have excellent capacitance, low leakage current, and superb stability and reliability.

The BFC237511302 has a capacitance of 11000 µF, making it perfect for a variety of DC applications. The low leakage current of 11.3A ensures that the capacitor will be able to store and release energy reliably over time. In addition, the epoxy coating provides excellent protection against fire and temperature fluctuations, making this capacitor a reliable choice for extreme environmental conditions.

In conclusion, the BFC237511302 is a versatile capacitor designed for high-current DC applications. Its low ESR, low leakage current, and excellent temperature resistance make this capacitor a great choice for challenging applications. With its unique features, the BFC237511302 is well suited for a variety of electronic applications.
