A capacitor is a small device that can be charged up with electrical energy, store it and then release it. Just like a rechargeable battery. But unlike a battery, it does not use a chemical reaction and it can only hold a very small charge. A very large capacitor can only light up an LED for a few seconds. They come in many shapes and sizes and a few are shown below. The bigger the capacitor, the more charge it will hold. Capacitor is made from two metal plates or metal foils separated by an insulator called a Dielectric material.

The Dielectric materials can be made from Ceramic, Mica, Polypropylene, Polyester, Electrolytic, Tantalum and even air.

The larger capacitors look like tubes, this is because the metal foil plates are rolled up with an insulating dielectric material sandwiched in between.

The value of capacitance is determined by

1.The size of the plates,

2.The distance between them,

3.The type of dilectric material used.

Keywords: Ripple Voltage, AC power supplies, audio amplifier, open-loop

Capacitors are used to couple each stage of an amplifier to the next, to help remove ripple voltages from rectified AC power supplies and they are also used to tune circuits to get the required frequency response, such as a tone control in an audio amplifier, or an RF or IF amplifier in a radio receiver front-end.

Capacitors are also used to bypass emitter resistors to improve the voltage swing and lower the AC output impedance of class A amplifier stages, and also used in negative feedback loops to stabilize an amplifier's open-loop gain.

We jb capacitors company professional produce MKT & MKP film capacitors, total 22 series. we have two representitive types used in Amplifier, audio, sound system. please check below.
