A 100 microfarad 16 volt electrolytic capacitor
Capacitance Tolerance
Ceramic disk capacitors for general applications usually have a tolerance
of +20 percent. Paper capacitors usually have a tolerance of +10 percent.
For closer tolerances, mica capacitors are used. It has tolerance value of
+2 to 20 percent. The letter after the capacitance numerical code indicates
the tolerance i.e.: M=20%; K=10%; J=5%. So a 103K capacitor is a
10,000pF or 10nF or 0.010µF 10% capacitor with 10 % tolerance.
Electrolytic capacitors have a wide tolerance. For instant, a 100µF
electrolytic with tolerance of 10 percent, +20 percent may have a
capacitance of 90 to 120µF.
