Film Capacitors

Film capacitors are non-polarized capacitors, which are constructed using thin metalized polyester or polypropylene film as the dielectric. These capacitors are used in a variety of applications in the electronics market due to their superior dielectric strength, small size, and inherent stability in comparison to other capacitor types.

F17724822000 Applications

Film capacitors are commonly used in power supply applications, such as the main inrush current limiters in notebook power supplies, switching power supplies, and server power supplies. In addition, film capacitors are frequently used in audio processing circuits, due to their low noise level, low distortion, and wide frequency response. They are also ideal for high frequency inductive circuits, because their dielectric strength is unaffected by the increased flux density caused by the large currents used in these circuits.

Working Principle

The working principle of the F17724822000 film capacitor is based on the fact that when a charge is placed on the surface of the thin metalized film, a uniform electric field is established within the capacitance. This electric field creates an electrostatic attraction between the surface of the film and the nearby surfaces. This attraction allows electrons to move freely through the air gap between the film and the surrounding surfaces, allowing current to flow across the capacitor. The presence of the electric field also creates a capacitive reactance, which can be used to regulate the amount of current flowing through the capacitor. By adjusting the amount of charge on the surface of the film, or by changing the distance between the two surfaces, the capacitance can be altered, resulting in a different capacitive reactance.

Stability and Reliability

Film capacitors are extremely reliable and stable, and are capable of operating in temperatures ranging from -40°C to +125°C. They are also highly resistant to shock and vibration, and can handle higher peak currents than other types of capacitors. Additionally, they possess excellent dielectric properties, with an often-cited dissipation factor of less than 0.1%. In conclusion, film capacitors like the F17724822000 are widely used in a variety of electronics applications, due to their small size, wide temperature range, high reliability and stability, and low distortion. The capacitance and reactance of a film capacitor can be adjusted by changing the charge on the film surface, or by changing the distance between the two surfaces. As a result, film capacitors offer precise control over the current flowing through the capacitor, and can be optimized for specific frequencies and applications.
