Film Capacitors

Film capacitors are a type of capacitor that are constructed using a thin plastic dielectric material. They are most often used in electronic circuits for filtering and damping signals, as well as for more general power supply applications. The capacitance can be changed by varying the thickness and width of the dielectric material, or by using different materials such as PTFE, polypropylene, or polystyrene. The dielectric material used in a film capacitor is normally characterized according to its dielectric constant and dissipation factor.

BFC237521753 is a film capacitor that offers high voltage, saturation current, dust-free air cooling, and space-saving design. It is specifically designed for high-frequency power supply applications. It has a voltage rating of 2,000 Vdc, a saturation current of 161 V/μs, and a capacitance range of 1.5–200 uF. The BFC237521753 has a wide operating temperature range of -25°C to +85°C.

Application Field

The BFC237521753 is used for high-frequency power supply applications such as switch mode power supplies, AC-DC and DC-DC converters, and switched capacitor DC-DC converters. It is also used for resonant circuits, frequency doubling circuits, and drive circuits of smart-phones and digital cameras. The capacitor provides excellent noise and pulse current handling characteristics in addition to its wide operating temperature range.

Working Principle

This film capacitor works in a similar way to other capacitors. It has two metal plates separated by an insulating material. When a voltage is applied across the plates, electrical charge is stored on the plates, which creates an electric field. The amount of charge stored depends on the capacitance of the device, which is related to the area and separation of the plates and the dielectric material between them. The charge stored on the plates is not dischargeable, so the capacitor acts as a barrier for energy stored electronically.

The BFC237521753 is manufactured using advanced winding methods, and it is spattered with a topcoat for maximum performance. Its low ESR and ESL ensure stable operation in high-frequency applications. The capacitors are well-suited for use in harsh environments and are designed to withstand temperature shock.
