Features and Use of Lighting Capacitors

Film capacitors differ in terms of product features, approvals and applications. Polarized capacitors may be operated safely with only one DC polarity. By contrast, nonpolar capacitors can be operated without regard to polarity. 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. Metallized Polypropylene Film Capacitors for Lamps.

Lighting capacitor or lamp capacitor (also called capacitor for lighting or capacitor for lamp), and is ideally energy- saving. It is special for grille lamp, and is ideally energy-saving. This product is characterized by its smallness, light weight, very low loss, long life-span, good self-healing characteristic and safe anti-explosion net as its dielectric layer. Lighting capacitor has another character of endure the high temperature. It can using in 40 degree to 85 degree.

Lighting capacitors work in largely the same way as conventional capacitors, except that the dielectric between the outside contacts is a chemical that gives off photons when the capacitor is charged. While this is not very useful for containing large amounts of power, other uses are possible. By making the contacts of the element transparent and leaving the capacitor with a very large surface area, (as opposed to compacting it through rolling) a reliable light source can be created.

Lighting capacitors can be designed for both series and parallel compensation of fluorescent lighting ballasts, mercury, metal halide, and sodium pressure lamps. Lighting capacitors are available in either thermoplastic or aluminum cases with a selection of terminal configurations and mounting options.
