Calculating additional capacitor codes
The most common capacitor code uses a first digit, second digit, and multiplier scheme:
3
Example 223J
= 22 x 10
pF
= 22 nF
= .022 µF
5% Tolerance
151K
= 150 pF
= .15 nF
= .00015 µF
10% Tolerance
Occasionally capacitors will have the value listed very plainly:
Example 47 pF
= 47 pF
4p7
= 4.7 pF (like the resistor values where the ‘M’ or ‘k’ split the numbers to indicate a decimal point)
