Film Capacitor

Capacitors are electrical devices that are used to store electrical energy.There are film capacitor,lighting capacitor and motor capacitor.

Features of Film Capacitor:

Less spoilage;
Very small dissipation factor;
Light weight;
Small inherent temperature rise;
Excellent self-healing stability;
Good capacitance stability,;
Safety and high reliability.

Typs of Film Capacitor:

Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials. Polyester film capacitors offer a high dielectric constant and high dielectric strength with volumetric. Metallized polyester film provides excellent self-healing properties, allowing capacitors to withstand high-pulsed voltages without breaking the dielectric. Polycarbonate film capacitors offer very low temperature dependency, wide operating temperature range, good long-term stability and low losses. Polypropylene film capacitors provide very low losses, low dielectric absorption, and high dielectric strength. They also offer very high insulation resistance and negative temperature coefficient. Polystyrene film capacitors provide extremely low losses, low dielectric absorption, good long-term stability, very high insulation resistance and a small negative temperature coefficient.

Application:

Film capacitors that are destined for sale in European Union (EU) countries must with Restriction of Hazardous Substances (RoHS). In the United States, film capacitors that are designed for military applications must meet military specifications (MIL-SPEC). Polyester capacitors are used in bypassing and coupling applications. Uses for polycarbonate capacitors include timers and filters, as well as high ambient temperature applications. Polypropylene capacitors are used in stable oscillators, sample-and-hold circuits, and pulse-handle circuits. Like other types of film capacitors, polystyrene capacitors can be used in timers and filters. Some film capacitor is applied to air-condition, electromotor, water pump, air compressor and so on.
