Capacitor Code Calculator
The capacitance of a capacitor is usually represented by a 3 digit-code imprinted on it.How to calculate capacitance from code
For a three-digit code, "xyz", the capacitance will be the number represented by the first two digits "xy" multiplied by 10^z pico-farads.
For two-digit and one-digit codes, the number represented directly translates to the number of picofarads.
Therefore, "220" and "22" both represent a capacitance of 22pF.
Often times, a letter follows the numeric code, and this represents the tolerance. A list of tolerances can be seen below.
