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:   Arrow Capacitance = 10nF

Tolerance = +/- 20%
Select Tolerance Code:     

Convert Values to Codes:

Enter Capacitance:   Arrow Code = 222

Tolerance Code = M
Select Tolerance:
