Film Capacitors

Film capacitors, also called plastic film capacitors, are made from electrode and dielectric materials which are laminated into thin layers or sheets. The capacitance is determined by the area of the electrode, the number of layers or sheets, and the spacing between them. In general, the film used as the dielectric material is made of Mylar, Polyester, Teflon (PTFE), Polycarbonate, Polypropylene, or Metallized Polypropylene. These capacitors can provide higher dielectric strength, greater temperature stability, high-frequency characteristics, and a wide capacitance range compared to other types of capacitors.

C4CAWUD3330AA1J is a film capacitor specifically designed for general applications. Its construction consists of two metal plates with a plastic film wrapped in between. The device has a wide capacitance range of 0.1 to 3300 pF and a rated voltage of 35V. The capacitance is stable over a wide temperature range of -55 to 125°C. The C4CAWUD3330AA1J is extremely reliable due to its low temperature coefficient, low resistance and high dielectric strength. As such, it is well suited for use in low-voltage signals, DC-DC converters, AC circuits and audio circuits.

Working Principle of Film Capacitors

Film capacitors’ working principle is based on the dielectric materials that it is made with. The dielectric material provides a dielectric constant, or a measure of the material’s resistance to hold a charge. When a voltage is applied between the two metal plates, the dielectric material creates an electric field that stores the charge. The amount of charge stored is determined by the length and spacing of the metal plates. The amount of capacitance that a film capacitor can store is directly proportional to the dielectric constant of the film material.
