Film Capacitors

The BFC237884303 capacitors belong to the family of Film Capacitors. These capacitors are known for their smaller size, strong insulation properties, heat tolerance, and high electromagnetic field compatibility. Film capacitors are produced by winding a dielectric film around an insulating form, and then injecting electrodes for connection. The layers of windings of dielectric film and electrodes create the selective capacitance. They also store energy in an electric field, characterized in Farads.

Field of Application

Film capacitors have many different uses, ranging from small signal applications to specialized fields such as power converters, high-energy pulse delivery, and switch damping. They are well-suited for use in the power grid, for data line protection, and in medical applications, as well as regenerative braking, motor drives, electric transportation, and drones. They are capable of operating at varying temperatures, with nominal temperatures ranging from -25˚C to 125˚C.

Working Principle

Film capacitors possess an excellent temperature resistance which makes them proficient at filtering and stabilizing power. As an alternating current (AC) travels through a film capacitor, it is exposed to the film’s alternating electrical field. This electrical field opposes and slows down the AC\'s current, thus providing a voltage stabilization. Similarly, as a direct current (DC) passes through a film capacitor, it too is slowed, or filtered, thus providing a current stabilization.The number of layers of dielectric film and the type of carriers used in the film determines its capacitance, with higher ratings of capacitance correlating to greater electrical energy storage and higher voltage ratings.

Voltage Rating

The BFC237884303 capacitors boast a voltage rating of 400VAC (400 volts alternating current). Higher voltage ratings help these capacitors be used in a variety of higher-voltage applications, as they have a greater ability to withstand higher voltages. It is important to note that a capacitor’s working voltage is not its voltage rating, and that a voltage higher than its rating should never be applied to it.

Conclusion

To conclude, BFC237884303 capacitors are a type of film capacitor used in a variety of applications and for different purposes. They can store electrical energy in an electric field and have a voltage rating of 400VAC, which makes them well-suited for many applications. They are capable of operating at varying temperatures, which makes them capable of being used in locations with varying worldwide temperatures. Finally, they possess excellent temperature resistance and are great at filtering and stabilizing power.
