Film Capacitors

A film capacitor, also called a plastic film capacitor, is a capacitor that uses plastic film as the dielectric. It is made up of two very thin metal foil sheets that are insulated by the plastic film and impregnated with oil. The capacitor is constructed by winding these two foil sheets onto either an air form core or an inexpensive plastic form. They are designed to withstand extreme temperatures, high voltage, and are particularly suited to AC pulses.

BFC237347185 Application Field and Working Principle

The BFC237347185 film capacitor is suitable for AC voltages ranging from 1KV to 25KV and is mainly used in a variety of high voltage applications, such as in high voltage electrical equipment, wind power equipment, pilot-operated relay systems, and large-scale electronic product sealing glue.

The working principle of the BFC237347185 film capacitor is based on the concept of capacitance. It has two plates with opposite charges separated by a dielectric. When the voltage applied to the plates changes, the relationship between the charge and the voltage changes as the dielectric is polarised. This results in the stored energy in the electric field between the plates. This produces a current flow through the dielectric, creating an electromechanical force.

The physical construction of the BFC237347185 film capacitor ensures that the stored energy is very low. This allows the capacitance to remain constant over a wide temperature range. It also allows the capacitance to be adjusted by simply adjusting the electrostatic charge applied to the dielectric material.

The BFC237347185 film capacitor is relatively simple in design and construction. Its excellent performance at high voltages makes it ideal for use in high voltage applications, which makes it an highly reliable and cost-effective solution for many projects.
