Working Principle of BFC238351243

The BFC238351243 utilizes a special construction of thin layers of polymer film with metal electrode layers to store electrical charge. The film is usually stack of thin alternately opposing layers of metal and polyester. The metal layers hold the electric charge, while the polyester layers act as separators, preventing electrical leaks and creating electrical insulation. The thicknesses of the layers are critical to achieving the desired capacitance.

When the capacitor is discharged, electric current flows from one of the metal layers into the polyester layer, across to the other metal electrode layer, and comes back through the other polyester layer. The voltage between the two metal layers causes the electric charges to move, a reaction known as capacitance. This reaction creates a relatively small amount of heat, which is dissipated by the surrounding air.

The BFC238351243 capacitor also features an extra layer of insulation between the metal layers, which helps to reduce inductance and increase capacitance stability. This insulation layer also helps to reduce electrical losses, allowing the capacitor to operate at higher frequencies. The extra insulation layer also helps to minimize Electric Field Insulation (EFI), which increases system efficiency and reduces failure rate.
