The capacitance of a capacitor tells you how much charge it can store, more capacitance means more capacity to store charge. The standard unit of capacitance is called the farad, which is abbreviated F. It turns out that a farad is a lot of capacitance, even 0.001F (1 milifarad -- 1mF) is a big capacitor.
To read a large capacitor, first find the capacitance value, which will be a number or a number range most commonly followed by µF, M, or FD. Then look for a tolerance value, typically listed as a percentage. Next, check the voltage rating, which is usually listed as a number followed by the letters V, VDC, VDCW, or WV.
C = Q V = Q Qd / ϵ0A = ϵ0A d. Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.
Not all capacitors are created equal. Each capacitor is built to have a specific amount of capacitance. The capacitance of a capacitor tells you how much charge it can store, more capacitance means more capacity to store charge. The standard unit of capacitance is called the farad, which is abbreviated F.
Capacitance Most capacitor data sheets specify the capacitance of a component in terms of rated capacitance, AC/DC capacitance, and charge-discharge proof properties. Details on how the capacitance of a component varies with temperature and frequency are usually provided under this subsection.
Check the voltage rating. If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for "Working Voltage"). This is the maximum voltage the capacitor is designed to handle. 1 kV = 1,000 volts.
