First digit is 0. Second and
third digits are significant
figures of capacitance code.
The fourth digit is the number
of zeros following.
Examples: 0101 = 100pF
0332 = 3300pF
M = 20%
Z = -20+80%
C = C0G/NP0
X = X7R
0 = Without
Note: The addition of a 4-digit numerical suffix code can be used to denote changes to the standard part.
Options include for example: change of pin length / custom body dimensions or threads / alternative voltage rating / non-standard intermediate capacitance values / test
requirements.
Please refer specific requests to the factory.
