The Capacitor

A device used to store charge in an electrical circuit. The Capacitor functions much like a battery, but charges and discharges much more efficiently (batteries, though, can store much more charge).

A basic capacitor is made up of two conductors separated by an insulator, or dielectric. The dielectric can be made of paper, plastic, mica, ceramic, glass, a vacuum or nearly any other nonconductive material. Some capacitors are called electrolytics, meaning that their dielectric is made up of a thin layer of oxide formed on a aluminum or tantalum foil conductor.

The Capacitor electron storing ability (called capacitance) is measured in Farads. One Farad is actually a huge amount of charge (6,280,000,000,000,000,000 electrons to be exact), so we usually rate capacitors in microfarads (uF = 0.000,001F) and picofarads (pF = 0.000,000,000,001F ). Capacitors are also graded by their breakdown (i.e., smoke) voltage. Capacitors rated for lower voltages are generally smaller in size and weight; you don't want to use too low a voltage rating, though, unless you enjoy replacing burnt-out capacitors in your creation.

Shean(Cangzhou) CORP LTD is one of the most professional manufacturer of medium frequency whole set equipment, elbow forming machine and Capacitor. We have been in this line for more than 20 years, our products are widely used in many foreign countries, covering metal smelting, keep heating, diathermanous, pipe bending, elbow machine, and power supply etc.
