WebTypical capacitance values range from picofarads ( 1 pF = 10 − 12 F) to millifarads ( 1 mF = 10 − 3 F), which also includes microfarads ( 1 μ F = 10 −6 F ). Capacitors can be produced … WebReal capacitors have a voltage rating that should not be exceeded. Since a capacitor has connection wires, it inevitably has a small parasitic resistance and inductance. The parasitic inductance can be important if the capacitor is expected to provide sudden bursts of current, such as when it is connected to the power pin of a digital chip.
