Film Capacitors

F17102471002 Application Field and Working Principle

Film capacitors generally refer to capacitors with a dielectric layer composed of plastic film. films such as polypropylene, polystyrene, polyester and polycarbonate, as well as mica and paper films. These capacitors have excellent electrical performance, such as small size, light weight, high insulation resistance, stable capacitance, low leakage current, good self-healing property, and can work stably in a wide temperature range. F17102471002 is a typical film capacitor. It applies in many fields and works according to certain principles.

Application Field and Performance Advantages

F17102471002 capacitors are widely used in industrial, military, automotive, aerospace and other power systems. In addition, it can also be used in personal electronic products such as computers, televisions, cell phones and other electronic devices. Due to its excellent performance, it is more suitable for high-end products. It has the following characteristics:

• Higher rated voltage, temperature coefficient, insulation resistance, and dielectric loss than electrolytic capacitors.
• High insulation resistance, stable capacitance.
• Withstand higher ripple currents and higher frequency signals
• No polarity, can be connected in any direction.
• Low dissipation factor, which can reduce the signal distortion.
• Can work stably over a wide temperature range.

Working Principle

The working principle of F17102471002 is the same as that of other film capacitors. It is composed of two or more layers of metal deposited on the surface of a dielectric film. When an AC voltage is applied, the electric field in the dielectric will make zigzag displacement of the charge carriers inside, so as to establish an electric field between the two electrodes and generate induction electricity, which eventually forms a specific capacitance. At the same time, due to the high electric field strength between the two electrodes, free electrons accumulated at both ends form a space-charge layer on the surface of the film, which can shield externally and internally applied electric fields, thus reducing the leakage current of the film capacitor.

Conclusion

F17102471002 is a typical film capacitor, which has excellent performance and is widely used in all aspects of industrial, automotive, aerospace and personal electronic products. Its working principle is the same as that of other film capacitors, which is a combination of the electric field in the dielectric and the space-charge layer on the surface of the film.
