Electronic capacitors are one of the most widely used forms of electronics components. However there are many different types of capacitor including electrolytic, ceramic, tantalum, plastic, sliver micaMineral silicates H2KA13(Si04 )3 naturally occurring. An excellent insulator resistant to temperatures. Used as a dielectric in capacitors and as insulation in high voltage, high temperature environments., and many more. Each capacitor type has its own advantages and disadvantages can be used in different applications.
The choice of the correct capacitor type is of great importance because it can have a major impact on any circuit. The differences between the different types of capacitor can mean that the circuit may not work correctly if the correct type of capacitor is not used.
Accordingly a summary of the different types of capacitor is given below, and further descriptions of a variety of capacitor types can be reached through the related articles menu on the left hand side of the page below the main menu.
Capacitor basics
there are many different types of capacitor, but they all conform to the same basic physical laws. These determine the basic way the capacitor operates, its value, i.e. the amount of chargeThe amount of electricity present upon the capacitor's plates. Also, the act of forcing of electrons onto the capacitor's plates. See CoulombA coulomb is the unit of electric charge. It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference.. it will hold and hence its capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive..
In order to understand some of the reasons why various forms of capacitor are used, it is necessary to look at the basic theory behind capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive..
