Film Capacitors

Film capacitors belong to a type of capacitors that are widely used in a range of applications due to their high performance and reliability. The BFC247990103 is an example of a Film capacitor that has been optimized over time for various applications. This article will discuss the application field and working principle of the BFC247990103.

Application Field

The BFC247990103 is a dielectric film capacitor that is mainly used in the medical, industrial and automotive industry. It is designed to be used in high temperature and humidity environments and is equipped with a low failure rate. It has a high insulation resistance, which ensures reliable performance over long periods of time. In addition, this capacitor has a high current endurance rate, making it suitable for use in ECUs, servos and power tool applications.

Working Principle

The BFC247990103 functions by storing and releasing electrical energy using the two dielectric layers — a dielectric film that consists of insulation, and a conducting film. When a voltage is applied to the capacitor, electrons of a certain polarity are attracted and pile up in one of the layers, resulting in an electric field between the two layers. This electric field allows the capacitor to store electrical energy. The more voltage that is applied to the capacitor, the higher the capacitance of the device, allowing for more energy to be stored.

When the voltage is released, the electric field between the layers is broken and the electrons stored in the dielectric film are pushed back into the conducting film, resulting in a release of electrical energy. The amount of this energy depends on the voltage applied to the capacitor and the capacitance of the device.

The BFC247990103 is also designed to have an anti-pulse current distribution circuit which ensures a more even discharge of capacitance when voltage is applied and released. This has been shown to help reduce the return current, reduce the influence of the public network and ensure stability in power supply systems even in extreme circumstances.

Conclusion

The BFC247990103 is a dielectric film capacitor that is mainly used in a variety of applications due to its high performance and reliability. It is designed to be used in high temperature and humidity environments and is equipped with a low failure rate. It has a high insulation resistance and a high current endurance rate, making it useful for a variety of applications. It is also designed to have an anti-pulse current distribution circuit which ensures a more even discharge of capacitance when voltage is applied and released.
