Capacitor

What is CAPACITOR?

Capacitor store electric charge.It is used in timing circuits, to smooth varying DC supplies, it is used in filtering because it easily pass AC SIGNAL but block DC SIGNAL.

What are the kinds of Capacitor?

There are many kinds of capacitor. They are categorized in polarized capacitor which belongs electrolytic and tantalum capacitor which has a positive and negative side. While the other kinds of capacitor is unpolarized which belongs ceramic capacitor, mylar capacitor,plastic film and so on. This days most capacitor are on chips size. It is used widely in most electronic consumer now, from lcd tv up to the latest electronics gadgets. But still in the power supply area you will see a typical capacitor like electrolytic and other unpolarized capacitor like mylar big sizes.
