Film Capacitors

Film capacitors, also known as film dielectric capacitors, are a type of power capacitor. They are made up of one or several thin layers of film dielectric sandwiched between conductive plates or spirals of foil. Capacitance is achieved by adjusting the number of plates, the length and width of the plates, and the thickness of the dielectric film. They are typically identified by a metallized or non-metallized film of polyester,polypropylene, paper, FEP, or similar dielectric materials with capacitance values ranging from 47pF to 0.047uF.

B32560J0474K289 Application Field and Working Principle

The B32560J0474K289 is a radial-lead, aluminum electrolytic, film capacitor. It is a power capacitor, which is suitable for AC applications like motor starting, filtering, and power factor compensation, as well as DC applications including switching power supplies, regulated power supplies, and other circuits requiring a higher voltage capacitor. It has a capacitance of 4700uF and rated voltage of 450V.

As a power capacitor, its working principle is simple and direct. When a voltage is applied across the plates, the dielectric film absorbs electric charges, storing electrical energy. As an alternating voltage is applied, this stored energy is released and passed through the circuit. When used in circuits with AC voltage, the capacitor acts as an impedance, limiting current and preventing fluctuations. In this manner, the capacitor acts as a filter, conditioning power before it reaches the load, and increasing overall efficiency.

The reliability of the B32560J0474K289 is further improved by its radial leads, which ensure good contact with the mounting surface, and its aluminum electrolytic housing, which prevents severe vibration. Its combination of robust design and low losses makes it well-suited for use in a variety of applications including motor starting, speed control, and EMI filtering.

In summary, the B32560J0474K289 is a robust and reliable film capacitor, suitable for a wide range of AC and DC applications. With its low losses and robust design, it is a reliable way to improve the efficiency and reliability of any power system.
