Film capacitors, sometimes referred to as “film dielectric” capacitors, are capacitors constructed using a thin layer of electrical insulation between a pair of parallel electrodes. They are also commonly known as “paper capacitors” due to their paper-like physical appearance. The BFC2370GB222 is a specific film capacitor model, and it has its own particular application fields and working principles.

Application Fields

The BFC2370GB222 is an industrial-grade film capacitor that can withstand a working voltage up to 650VAC and a peak voltage of 1.1KVAC. It is also highly temperature-resistant, with an operating temperature range of -25°C to +90°C. Typical application fields for the BFC2370GB222 include power conditioning and filtering, DC roller motors and drives, AC motors and drives, welding, LED lighting, and energy storage. This film capacitor can also be used in high frequency amplifier applications. In addition, it is widely applicable in other general-purpose circuit applications, such as oscillators, choppers, and inverters.

Working Principle

A film capacitor stores energy in the form of an electric field between a pair of electrodes. The electrodes are typically made of metal foil, etched with a pattern of egg-crate-style “fingers” to increase their surface area and charge-holding capacity. This increases the capacitance, which is the capacitors primary electrical characteristic. It is measured in farads (F). The BFC2370GB222 has a capacitance rating of 4.7uF.

The dielectric, or insulation, between the electrodes is the primary component responsible for the capacitors performance. In the case of the BFC2370GB222, the dielectric is made of high-quality polypropylene film. The dielectric material creates an electrical field between the two electrodes that stores energy in an electric field. This field is created by allowing a voltage difference to exist between the two electrodes, which effectively binds the two electronically.

The electric field created between the two electrodes of the BFC2370GB222 will decay over time, acting as a filter component that can reduce electromagnetic and radio frequency interference in power supplies and other sensitive circuitry. The BFC2370GB222 also offers excellent electrolytic resistance, high insulation resistance, and low dissipation factor (DF).

In summary, the BFC2370GB222 is a high-performance film capacitor suitable for a variety of industrial applications. Its stable working voltage and wide operating temperature range make it a great choice for power conditioning and filtering, as well as general-purpose circuit applications. It offers excellent electrolytic resistance and low dissipation factor along with high insulation resistance, enabling reliable performance in a variety of environmental conditions.
