Introduction

Film Capacitors, as a kind of capacitors characterized by a flat polyester film with charged metal electrodes on either side, have found wide applications in various electrical and electronic equipment. Among them, BFC237222104 are among the most popular film capacitors, and this article aims to introduce their application field and working principle.

Application Field

Originally used for radio frequency applications such as in TVs, BFC237222104 are now used widely in various audio applications. Specifically, their high resistivity and voltage resistance makes it possible to reduce the loud pops and other static noises in audio equipment. Besides, their small form factor and lightweight also attract many consumers who are looking for portable audio solutions. In addition, other common applications of BFC237222104 include power supplies, various industrial machines and electrical control systems. By appropriately combined with other components, BFC237222104 could also be used in filtering circuits, voltage dividers, coupling and clipping circuits, and time delay circuits.

Working Principle

Similar to other capacitors, BFC237222104 employ two parallel metal plates, separated by a dielectric material, in order to store electric charge. When connected in parallel to an electric circuit, the value and nature of the dielectric material determines a capacitor’s ability to store and hold electric charge. In the case of BFC237222104, its unique dielectric material-polyester film provides excellent insulation properties, high voltage breakdown strength, and special absorbents which guarantee low-loss characteristic and temperature stability that are highly desired in most electronic applications.Moreover, the two metallic plates used in BFC237222104 are designed for maximizing charge storage capacity while minimizing physical volume, making them ideal for small form factor applications. As electric current passes through the two plates, the charges are stored within the dielectric, and the effective capacitance of BFC237222104 is determined by the area of the plates and the distance between them.

Conclusion

In summary, BFC237222104 are well-designed capacitors with an excellent combination of features that make them highly desirable in a range of applications, such as audio filtering and amplifying, power supplies, and electrical control systems. By exploiting their dielectric property and excellent physical characteristics, BFC237222104 have surpassed their counterparts to become one of the most common film capacitors in the market.
