Film Capacitors

Film capacitors have been used in many applications ranging from power electronics to signal processing. BFC237021123 is one type of film capacitor that is commonly used in these applications due to its robust design and low tradeoff between capacitance, contact resistance and power dissipation. This capacitor is made up of a thin dielectric film, which is sandwiched between two electrodes.

Application field of BFC237021123

BFC237021123 is often used as a power supply smoothing capacitor in many fields, such as computers, vehicles, AC motor speed control, optical power system, UPS, wind power conversion and energy storage. This capacitor is also used in switching power supply and DC/DC converters for power conditioning or energy storage. As a result, the applications of BFC237021123 are universal, and the usage of this capacitor can save the cost and the volume.

Working Principle of BFC237021123

The BFC237021123 works on the same principle as other film capacitors. When voltage is applied across the capacitor, electrons are drawn to the negative plate and leave the positive plate, thus creating an electric charge. Then, depending on the voltage applied, the capacitor will store a corresponding amount of energy equal to the energy stored in an electric field. Some of this charge can remain stored in the capacitor far after the application of voltage, thus allowing the capacitor to act as a reservoir of energy.

The BFC237021123 has an advantage of a large capacitance range. It can store up to 97F at 125VDC and the rated capacitance range is from 0.22 uF to 3.3 F at 125 VDC.The capacitor is also designed to operate with a wide temperature range, from -40 to +85 degrees Celsius. This makes the capacitor suitable for many extreme temperature conditions. On the other hand, its high-frequency loss also can be neglected at frequencies below 100kHz.

Conclusion

The BFC237021123 film capacitor is an ideal choice for many applications due to its reliability, low cost and robust design. Its application field is diverse, ranging from power conditioning to signal processing. Furthermore, its large capacitance range and wide operating temperature range make it possible to work in extreme conditions. Finally, its low-frequency loss ensures that this capacitor can be used effectively in many applications.
