Understanding basic capacitor construction and how different materials can affect their characteristics will aid in choosing the proper capacitor for a given application. The unit of capacitance is the farad. For 1 farad of capacitance, 1 coulomb of charge is stored on the plates when. All capacitors are formed with the same basic structure.
After the calculations have been done for the basic electrical requirements, there are still a lot of possible choices for device selection. Within that range, there may not be a "wrong" choice, but there are certainly good, better and best choices. The best choices will have a meaningful impact on physical size of the finished circuit, cost, power efficiency and reliability.

There are two other important characteristics of practical capacitors namely, Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL). Equivalent Series Resistance is the resistance of the capacitor due to its metal parts.
For a small-sized ceramic capacitor, the nominal capacitance can be of the order of one pico-Farad, (1 pF ). Whereas, the large-sized electrolytic capacitors can have a nominal capacitance of the order of one Farad (1 F) and thousands of Farads. (2). Capacitor Characteristics – Tolerance:
Capacitance variation due to operating voltage and temperature must be very low to keep the available load current stable. Capacitance drop during the lifetime of the capacitor must also be kept very low. For most applications with this topology, the input capacitance will be between 100 nF and 1000 nF.
The stipulations for individual capacitor series are in accordance with the CECC type specifications. The rated or operational pulse rise time is specified as 1/10 of the test pulse rise time. The pulse rise time F given in V/µsec is also indirectly the maximum current capacity.
The impedance of an ideal capacitor is only the reactance Z = X = ωC 1 = 1 . For 2πfC There are also advantages to be considered regarding the placement of a resistor in the input line. If we connect a relatively big input capacitor to the grid power, it may draw so much current in the first charging cycle that it could trip a circuit breaker.
The normal working temperature for most practical capacitors is ranging between -30 °C and +125 °C. The permittivity of the dielectric material between two conductive plates of the capacitor changes with temperature.
