Film Capacitors

Film capacitors, also known as film electric capacitors or film capacitors, are widely used as an important passive component in circuit and electrical circuit. Film capacitors are based on segmentation and insulation thin film technology. They are made of different metal films and organic dielectric films (Polycarbonate Film and Polyester Film). Compared to traditional ceramic capacitors, film capacitors offer superior performance in terms of temperature stability, volumetric efficiency, dielectric losses, and stability.

BFC246969273 Application Field and Working Principle

The BFC246969273 is a polyester film capacitor, designed for power supply line filtering, smoothing, coupling, bypass and electronic noise suppression applications. This type of capacitor is perfect for applications which require high insulation, low loss, low voltage, and stability over temperature. It also enjoys a wide application in audio speakers, power equipment, computers and other electronic equipment.

The capacitor is composed of two metal foil electrodes and an insulating polyester film as the dielectric. The positive electrode is slightly thicker than the negative. By using a film which is made of polyethylene terephthalate (PET) as the dielectric, the capacitance of the capacitor can be increased without increasing its size. As the thin film is evenly distributed between the two electrodes, it provides a uniform electrical field with high capacitance. When the material is connected to an AC or DC power supply, it allows the electricity to flow from one electrode to the other, creating a partial electrical field of attraction between them. Through this electrical field, the capacitor stores the electric energy.

The BFC246969273 has a maximum operating temperature range of -55°C~ +125°C. Its Capacitance ranges from 0.0033uF to 0.022uF. Its loss tangent is less than 0.001, and its insulation resistance is more than 500 M-ohms. In addition, its insulation voltage is 250VAC/DC, its dielectric strength is 2.75KV and its ripple current is 11.3 mA/V.

The BFC246969273 is particularly suitable for applications which require high temperature stability, low loss, and low voltage. They are used in power supplies, audio speakers, power equipment, computers and other electronic equipment. The BFC246969273 also has a wide range of frequency responses and is known for its excellent noise suppression characteristics.
