Electrolytic capacitors with letters on the level of accuracy can be compared below.

Expressed by letter: D - 005 - ± 0.5%; F - 01 - ± 1%; G - 02 - ± 2%; J - I - ± 5%; K - - Class II - ± 10%; M - Class III - ± 20%.

The accuracy level of a commonly used capacitor (that is, the error range) is the same as that of a resistor.
