Film Capacitors

BFC236722274 Application Field and Working Principle

A film capacitor, or ‘film’ for short, is a common type of capacitor that uses a thin plastic film as its dielectric. It consists of a dielectric core that is coated on each side with a conducting metallic material that acts as electrodes during electrical operation. This type of capacitor is widely used in many electronic circuits, due to its ability to store energy efficiently over a wide range of voltage and capacitance values. The type of film material used, as well as the amount of coating, determine the characteristics and performance of the capacitor.

The BFC236722274 film capacitor from Mobiadek Corporation is an AC-rated film capacitor that can handle up to 450 volts. It is insulated by a material with a dielectric strength of 6.8 kV/mm and provides a large capacitance of 22.7µF for up to +85ºC. The design and construction of this capacitor makes it suitable for use in many electronic applications, such as motor control circuits, power supplies, switch mode power supplies, and energy-saving equipment.

Working Principle

The working principle of a film capacitor is based on the dielectric properties of the thin plastic film used as its core. As the distance between the electrodes is changed, the capacitance of the capacitor will vary. This variation in capacitance is due to the change in the dielectric constant of the film. When a DC voltage is applied to the capacitor, the charge stored in the capacitor will remain constant, except for slight leakage current. When a varying voltage or current is applied, the voltage across the capacitor will change based on the capacitance of the film.

Applications

The BFC236722274 film capacitor from Mobiadek Corporation is a versatile device that can be used in a variety of applications. Due to its high voltage rating, it is suitable for use in high voltage circuits, motor control circuits, and switch mode power supplies. The large capacitance of this device makes it ideal for use in energy saving devices and electronic filters. The small size and weight of this capacitor makes it ideal for use in portable electronic equipment and communication equipment.
