Part of Electronics For Dummies Cheat Sheet (UK Edition)

Capacitor ratings aren’t all that precise, but you can at least work out how imprecise the ratings are by deciphering the following letter tolerance codes.

Code Tolerance
B ± 0.1 pF
C ± 0.25 pF
D ± 0.5 pF
F ± 1%
G ± 2%
J ± 5%
K ± 10%
M ± 20%
Z +80%, –20%
