Film Capacitors

A film capacitor, or plastic film capacitor, is a passive component consisting of a strip of plastic film impregnated with a chemical solution called dielectric or dielectric material. It is often referred to as an electronic component on a circuit board, and its purpose is to store energy, control timing, filter power, or act as a voltage divider. A variety of different capacitances can be created by altering the film properties or the number of conducting metal layers on the film.

The most common type of film capacitor is a polypropylene (PP) film capacitor. The construction of a PP film capacitor typically consists of a polypropylene film with metal electrodes and bushings, a lead frame and two outer epoxy covers. Its capacitor element contains a metal-oxide-film dielectric system that is highly dielectric and reliable. This dielectric material is reliable up to 250°C and has a very stable capacitance-temperature characteristic with a low dissipation factor at various temperatures. The dielectric can also be used in high-voltage applications and high-temperature environments.

F17724222003 is one type of film capacitors, with rated voltage at 250V AC, its application area covers paper machine data collection, variable speed drive, industrial automation, etc. It has advantages of small size, low equivalent series inductance and lower dissipation factor, which makes it useful for applications requiring a high-capacity storage at a high frequency. It also has excellent AC performance up to 100 MHz.

In terms of F17724222003 working principle, its capacitor element contains a metal-oxide-film dielectric system that can effectively store energy and manage timing. The structure mainly consists of four layers, the first one is the polypropylene film, which is the conductor, the second and the third layers are the multiple thin metallized layers of aluminum, which are the electrodes, and the fourth layer is the insulating cover protecting the internal structure from moisture and dust. When the capacitor is charged, electrical energy is stored within the electrostatic field that forms between the electrodes. When voltage is applied to the capacitor, the electrical energy stored is released back into the circuit.

The film capacitor has good temperature stability, low dielectric loss, and good high-frequency characteristics. It offers a wide range of applications as an excellent choice for general-purpose film capacitors. F17724222003 film capacitors are popularly used in wireless communication systems, broadcasting systems, as well as automotive and industrial market.
