Capacitor Code Calculator

These calculators can convert the 3-digit value codes and alphabetical tolerance codes found on some capacitors into the corresponding value and vice-versa. Both parts of each calculator work separately - you do not have to enter both value code and tolerance code.

Convert Codes to Values:

Enter 3-digit Value Code:		Capacitance = 10nF Tolerance = +/- 20%
Select Tolerance Code:      C D F G J K M Z

Convert Values to Codes:

Enter Capacitance:   Microfarads Nanofarads Picofarads		Code = 222 Tolerance Code = M
Select Tolerance:     +/- 0.25pF +/- 0.5pF +/- 1% +/- 2% +/- 5% +/- 10% +/- 20% -20% +80%
