Introduction

Film capacitors are electrostatic devices that store energy in an electric field between layers of metallized polypropylene. The polypropylene film is dielectric in nature, and the metallized layers act as the electrodes. The electrodes and the dielectric are housed within an insulation body, which is used to protect the device from environmental effects. It is most commonly used as a power conditioning component in many industries, including medical, automotive, and consumer electronics.The BFC237221474 is a film capacitor manufactured by the Chinese manufacturer "An Shan". It can be used in a variety of applications, from power conditioning and filtering in medical and automotive electronics, to consumer electronics and power electronics. This capacitor is a polypropylene film type, with a rated voltage of 500V DC, a capacitance of 2.2mF, and a temperature coefficient of -30ppm/K.

Application Field

The BFC237221474 is a polypropylene film capacitor that is widely used in medical, automotive, consumer electronic, and power electronics applications. In medical applications, this capacitor is used in a wide variety of medical equipment, such as CAT scanners, x-ray machines, ECG machines, among others. It also finds application in automotive electronics, particularly in power conditioning and filtering. Additionally, the BFC237221474 is used in consumer electronics applications, such as amplifiers and TVs, as well as power electronics applications, such as converters.

Working Principle

A film capacitor consists of two or more capacitive electrodes, generally a film layer, and an insulating or dielectric layer. The two electrodes are separated by a dielectric layer that can be composed of various materials, including plastic, paper, glass, or metal. When the two electrodes are connected to a DC source, a voltage is applied across the electrodes and electric field is created. This electric field causes electrons to flow through the dielectric layer, resulting in the accumulation of charge.When alternating current flows through the capacitor, the buildup and loss of charge causes the material to store electric energy, inducing a current in the two electrodes. This current is due to the accumulation of electric charge produced by the alternating current. This electric field also produces a reverse voltage, which resists any further current from flowing through the dielectric layer. This reverse voltage is known as the capacitor’s reactance, and the sum of the direct and capacitive voltage form the total capacitive impedance of the capacitor.

Conclusion

The BFC237221474 is a polypropylene film capacitor manufactured by An Shan. This capacitor is used in a variety of applications, such as medical, automotive, consumer electronic, and power electronics. It has a rated voltage of 500V DC, a capacitance of 2.2mF, and a temperature coefficient of -30ppm/K. The working principle of this device relies on the accumulation of charge by the alternating current that passes through it, which creates a reverse voltage that resists further current from flowing through its dielectric layer.
