Look for a tolerance value. Some capacitors list a tolerance, or the maximum expected range in capacitance compared to its listed value. This isn''t important in all circuits, but you may need to pay attention to this if you require a precise capacitor value.
The capacitance of a capacitor can be defined as the ratio of the amount of maximum charge (Q) that a capacitor can store to the applied voltage (V). V = C Q. Q = C V. So the amount of charge on a capacitor can be determined using the above-mentioned formula. Capacitors charges in a predictable way, and it takes time for the capacitor to charge.
