Film capacitors are components used in power structures and electromechanical devices, and provide electrical and dynamic coupling capacitance in a wide variety of circuits. Among them, BFC237872123 film capacitors have been widely used in various fields due to their low leakage rate, high reliability, and high stability. In this article, the application field and working principle of BFC237872123 film capacitors are introduced in detail.

Application Field of BFC237872123 Film Capacitors

The application field of BFC237872123 film capacitors is mainly in the high-frequency power system. Its voltage range is low voltage to ultra-high voltage. It is mainly used in high-frequency communication systems for smoothing, isolation, coupling, energy storage, and voltage regulation. The rated frequency is common in high and ultra-high frequency, and is suitable for circuits working in high-frequency and ultra-high frequency. It is used in intermediate frequency circuits, video circuits, communication circuits, electronic equipment, frequency counting circuits, monitors, generators, and car electronic components.

In addition, BFC237872123 film capacitors are suitable for AC grade motor fields. It has the characteristics of high insulation resistance, high stability, not easy to age, long life, etc. It is also highly resistant to temperature, humidity, and shocks. That is why BFC237872123 is used for motor running. It is also required in computers, lighting, medical equipment, aerospace and other fields.

Working Principle of BFC237872123 Film Capacitors

The basic working principle of BFC237872123 is, like other capacitive devices, the difference of potential between two terminals. The two terminals are usually separated by special insulating materials (such as polypropylene or thermoplastic films). The first terminal of the capacitor is connected to the power supply. When the voltage at the two terminals is equal, the charge balance is achieved and the current stops. Otherwise, an electric current will flow in the circuit.

The BFC237872123 film capacitor capacitance value is determined by the size and thickness of the insulating material, as well as the number of layers of the insulating material. The transient characteristic of the film capacitor is also determined by the design of the insulating material. A number of air gaps between the conductor and the insulating material will form, resulting in a lower capacitance value, and the transient characteristic is better than ordinary capacitors.
