Introduction to Film Capacitors

Film capacitors (often called polyester or polypropylene capacitors) are a type of capacitor constructed using thin dielectric film under high pressure contact with two aluminum electrodes and wrapped in a plastic casing. They are characterized by high stability and maintain their rated value over wide temperature ranges, good pulse bearing capacity, and a very good insulation resistance. Film capacitors usually have a better performance than ceramic capacitors because of their dielectric\'s higher dielectric strength.

BFC2370FB683 Applications And Working Principle

The BFC2370FB683 is a film capacitor with a DC working voltage of 500V. It has capacitance of 68nF and a tolerance of 10%. The BFC2370FB683 has a dielectric of polypropylene and a capacitance range of 10nF to 220nF. It has a wide operating temperature range from -55°C to + 125°C and a dissipation factor of 0.17.Film capacitors work by storing energy in an electrical field. As an electric charge is applied to the plate facing, it is repelled by the opposite plate, causing the electrical field to weaken and resulting in the capacitor storing energy. When this charge is increased the capacitor stores more energy until it reaches its limit. At this point, the capacitor starts to discharge the stored energy and the voltage across the capacitor is reduced. This process is repeated until the capacitor is completely discharged and then the capacitor can be recharged.The BFC2370FB683 is a capacitor that is used primarily for filtering, by-pass and decoupling applications. In filtering applications, the capacitor acts as an electronic low-pass filter, allowing the AC cycle while blocking any DC voltage. In by-passing applications, the capacitor is used to divert high-frequency current around an electronic component, thus improving system performance. Lastly, in decoupling applications, the capacitor is used to separate one component from another.

Conclusion

The BFC2370FB683 is a film capacitor with very good performance characteristics, making it ideal for a wide range of applications. It is especially suited for filtering, by-pass and decoupling applications, due to its high stability and wide operating temperature range. With its dielectric’s high dielectric strength, the BFC2370FB683 is sure to be a great addition to many film capacitor designs.
