Standard Capacitor Values & Color Codes
Over time, a series of standard capacitor values have evolved, just as with 
resistors and inductors. Capacitors are available in a huge range of package 
styles, voltage and current handling capacities, dielectric types, quality 
factors, and many other parameters. Still, they largely hold to this range of 
values.

Capacitors are one of the four fundamental types of passive electronic 
components; the other three are the inductor, the resistor, and the memristor. 
The basic unit of capacitance is the Farad (F).

In order to obtain other values of capacitance, it is necessary to use parallel
and/or series combinations. Often, complex combinations are used in order to
satisfy multiple requirements such as handling large voltages while still 
providing the correct amount of capacitance.

If you need to provide occasional tuning of a circuit, then it is necessary to
use a variable capacitor. That can take the form of a manually adjusted
capacitor, or an electrically tuned capacitor like a varactor diode (varicap).
