Film capacitors, also known as plastic film capacitors, refer to capacitors made of plastic film as a dielectric medium. BFC237341684 is an film capacitor developed by Shenzhen BlueOcean Technology Co., Ltd, widely used in many applications. This article will discuss the application fields and working principle of BFC237341684.

Firstly, BFC237341684 is mainly used in power electronic equipment, automotive electronics, communication systems and other fields. It is a high-performance product with a rated voltage of 630VDC and a capacitance range of 0.047μF to 2.2μF. This capacitor has good mechanical strength, heat resistance, high insulation resistance and strong self-healing ability, and it\'s so reliable that it attains UL certification. Therefore, BFC237341684 is suitable for many applications such as motor control, switch mode power supply, plastic welders, AC DC inverter, dimmers, and frequency converters.

Secondly, in terms of working principle, film capacitors use plastic films such as polyethylene, polypropylene, polycarbonate, etc., to insulate and separate two metal electrodes to form a dielectric medium. The conductive material of the film material accounts for about 70% of the volume of the capacitor. As an example, BFC237341684 has an extended metal (EM) electrode, with an inner layer of tin foil, outer and mid layers of aluminum foil, and a polypropylene as the dielectric layer. When a voltage is applied to the capacitor, the electric field generated on the surface of the dielectric layer causes the electrons to move away from the surface and form a polarization, which creates an electric dipole layer. Then, electric charges accumulate on both sides of the dielectric to form an electric field in the dielectric layer, leading to the increment of transient current and the decrease of the voltage across the capacitor. This is the working principle of the BFC237341684.

In conclusion, BFC237341684 is a reliable and high-performance film capacitor developed by Shenzhen BlueOcean Technology Co., Ltd. It is widely used in power electronic equipment, automotive electronics, communication systems and other fields due to its strong self-healing ability, excellent corona prevention and climate adaptability. In terms of working principle, BFC237341684 applies a dielectric plastic film between two electrodes, and when a voltage is applied, an electric dipole layer is created, leading to the increment of transient current and the decrease of the voltage across the capacitor.
