Film Capacitors

Film capacitors are electronic components that are used to store electrical charge. They are also known as film dielectric capacitors or polyester capacitors. Film capacitors are classified as dry non-polarized capacitors and are quite different from the more common electrolytic capacitors. The primary properties of film capacitors are their light weight, high capacitance, and low leakage current.

Film capacitors boasting a high dielectric strength have a wide usage in industrial and household applications. Specific capacitors are often designed much in the same way as other forms of capacitors, but with material used in the construction of the capacitor which presents a greater electrical insulation resistance.

BFC2370GH222 application field and working principle

BFC2370GH222 film capacitor is a large d.c. blocking currents capacitor that is used mainly in AC input line protection and decoupling of power supplies in flux welding machines and other high power applications. It is also used in power line filtering and dampening of rectifier input voltages. The particular BFC capacitor has been designed for use in the power supply of circuit boards and line filters such as EMI/RFI.

A BFC2370GH222 film capacitor is a non polarized type capacitor with a working voltage of 250V and a rated capacitance of 3,700μF. It is an integrated film capacitor array with an operating temperature range of -25°C to +85°C and a capacitance range of up to 500μF. This capacitor has a robust construction, excellent electrical properties and superior performance especially in high voltage applications.

In terms of working principle, the BFC2370GH222 integrated film capacitor array works by forming a barrier between the opposite electrodes with a non-conductive polymer film. It captures electric charge when a voltage is applied between the two electrodes. When the voltage is removed, the electric charge is released. This makes the BFC2370GH222 ideal for blocking DC current in power supply and line filtering applications.
