Film Capacitors

Film capacitors, also known as plastic film capacitors, polyethylene terephthalate (PET) film capacitors, and mylar capacitors, are passive two terminal electrical components used to store energy electrostatically in an electric field. A dielectric film, sandwiched between two electrodes, provides the main electrical properties of the capacitors. Film capacitors possess many features that make them very useful in many common electrical applications. They are easier and cheaper to manufacture than other capacitors, and they generally have higher peak operating voltages. They have excellent insulation characteristics and they possess a higher level of stability than other capacitor technologies, making them the preferred choice for many high-frequency and power applications.

F17102471900 Application Field and Working Principle

F17102471900 is a kind of film capacitor which is designed for surface mounting. It is based on polyester dielectric film and its type is plastic screw terminal. The capacitance range is from 47nF to 10µF. F17102471900 is suitable for various circuits such as input and output of switching power supplies, snubber circuit, energy storage, circuit and by-pass. It also can be used as input of DC-link.

The working principle is that it stores electric energy in electrostatic field. The electrical characteristics of material consist of electrodes and dielectric which decide the capacitance of film capacitor. Its components are metalized polyester film, electrodes, terminal and epoxy resin. With regard to its structure, it is a combination of an anode and a dielectric layer. When the positive and negative voltage of the capacitor are set high enough, charges would be stored in dielectric, electrical energy is therefore attained.
