Film capacitors refer to capacitors made of film as the dielectric layer. The film capacitor is an important component in electronic components, which is widely used in fields such as radios, TVs, monitors, audio power amplification, and computers. The BFC246855394 is a film capacitor, which is widely used in cell phones, medical equipment, instrument amplification and communication receivers with its excellent performance.

Application Fields

The film capacitor BFC246855394 is mainly used in cell phones, medical equipment, instrument amplifiers and communication receivers. Generally, the BFC246855394 is used in applications that require high voltage and capacitance. It usually plays the role of filtering, decoupling, signal coupling and signal compensation. For example, the BFC246855394 is used in 3G CDMA, in order to reduce the radiation, reduce the number of antennas used, and reduce the volume of the phone. In medical equipment, the BFC246855394 is used in the control circuit of the defibrillator to ensure the safety of medical personnel. In instrument amplifiers, the BFC246855394 is used to improve the signal-to-noise ratio of the amplifier and reduce distortion. In communication receivers, the BFC246855394 can reduce the interference from the contact part of the signal line and improve the receiving sensitivity.

Working Principle

The working principle of the BFC246855394 is based on the electrostatic capacity. Generally, it is composed of two metal plates (or one metal plate and one metal film) insulated and separated by a thin insulating film. When a voltage is applied to the pair of plates, a certain charge will appear on the two plates, thus forming an electric field. This electric field penetrates the insulating film. According to the distribution of charges and electric field around the two metal plates or metal films, a capacitive coupling appears between them. This capacitance is also known as electrostatic capacity.

The BFC246855394 is a metallized polyester film capacitor. It has the advantages of small size, light weight, strong anti-interference, stable performance, and long life. It can work normally in the temperature range of -55 to +125 degrees Celsius, and can work reliably with a wide voltage range. In addition, its volume resistivity is more than 1000 times higher than that of paper capacitors, which can significantly reduce the risk of fire and ensure the safety performance of the circuit.

Conclusion

The BFC246855394, as a film capacitor, is widely used in fields such as cell phones, medical equipment, instrument amplifiers and communication receivers. Its small size, light weight, strong anti-interference, stable performance, and long life make it an important component of electronic products.
