Capacitor is a device that stores energy created between a pair of conductors. An insulator (also called dielectric) of some kind is usually placed between the plates. The conductors are plates / electrodes which store opposite charges between them. The amount of charge a capacitor can hold can be found by multiplying "capacitance" with the "potential difference" between the plates. Capacitance is the amount of charge that can be stored on a capacitor plate. Silver-Mica - This uses mica as a dielectric. Mica capacitors have good stability because their temperature coefficient is small. Because their frequency characteristic is excellent, they are used for resonance circuits, and high frequency filters. Also, they have good insulation, and so can be utilized in high voltage circuits. It was often used for vacuum tube style radio transmitters, etc. Mica capacitors do not have high values of capacitance, and they can be relatively expensive. Generally, Variable Capacitors - They are also called trimmer capacitors or adjustable capacitors. They usually have ceramic or plastic as a dielectric. Most of them are color coded to easily recognize their tunable size.

capacitors are made of Tantalum with a symbol Ta, and atomic number 73. Tantalum can easily form an oxide layer on the surface layer on the tantalum foil. The oxide layer forms the dielectric and the electrolytic solution on the other side forms the other plate needed for capacitor to work. Because the dielectric can be thin a high capacitance can be achieved in a small space. They are mostly used in pagers, personal computers, and automotive electronics. They are better than electrolytic capacitor. Their capacitance doesnt change with temperature. These capacitors use a molecule-thin layer of electrolyte. Since energy is inversely proportional to the thickness of dielectric layer these can carry enormous amount of energy. Usual capacitance is about 0.47 Farad. The electrodes are made of activated carbon, which has a high surface area per unit volume. A significant amount precaution must be taken when using this kind of capacitor. This is a good quality capacitor which is stable with temperature and has low drift. The dielectric is made of polyester or Mylar. It has good tolerance level too.
