Film capacitors or plastic capacitors are electrolytic capacitors that make use of plastic film as the dielectric material instead of electrolytes. The BFC2373GL123MD is one such capacitor available in the market that has a wide variety of applications. In this article, the application field and working principle of the BFC2373GL123MD will be discussed in detail.

The BFC2373GL123MD is an axial leaded, two-part film capacitor that is primarily used for low-voltage, high-frequency applications, such as switch-mode power supply, broadcast transmitters, and DC-DC converters. It is designed to provide protection against over-voltage transients, RF interference, and to reduce noise in circuits. The device is equipped with a self-healing feature, which allows it to discharge residual and unwanted energy. Due to this feature, it also offers increased safety and reliability.

The BFC2373GL123MD has a capacitance of 0.001microfarad and is rated for a voltage of 630V. The device is designed with a two-layer structure with a polypropylene film as the dielectric material, an aluminum foil layer as the electrodes, and an epoxy case. The two-layer structure provides better performance and increases the capacitor time constant. The capacitor is designed to handle high-frequency signals up to 1GHz.

The working principle of the BFC2373GL123MD is based on the generation of electrical field by the conductive electrodes of the two layers of the capacitor. When a voltage difference is applied to the two conductive electrodes, an electric field is created. The field is generated due to the difference in potential between the two electrodes. The electric field causes the electrons in the aluminum foil to move in a certain direction, thus creating the electric current that is used to determine the capacitance.

The BFC2373GL123MD is also designed with a self-healing feature, which is responsible for discharging excess electric charge stored in the capacitor. As the electric charge accumulates, it causes the aluminum foils to expand and contact each other, thereby allowing the excess charge to discharge. This feature ensures that the capacitor will not be overloaded and can handle high voltages without any damage.

In conclusion, the BFC2373GL123MD is an axial leaded, two-part film capacitor that is primarily used for low-voltage, high-frequency applications such as switch-mode power supply, broadcast transmitters, and DC-DC converters. The device is designed with a two-layer structure with a polypropylene film as the dielectric material and aluminum foil layer as the electrodes. The working principle of the BFC2373GL123MD is based on the generation of electrical field by the conductive electrodes of the two layers of the capacitor. The device is also equipped with a self-healing feature, which allows it to discharge residual and unwanted energy. The BFC2373GL123MD offers increased safety and reliability and can handle high-frequency signals up to 1GHz.
