Electronics Capacitor Tolerance Code

In electronic circuits, the tolerance of capacitors can be determined by a code that appears on the casing. The code is a letter that often follows a three-digit number (such as 130Z). The following table outlines tolerance values for some common capacitors.

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%
