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. Details of capacitor markings can be found in the technical data section.

Convert Codes to Values:


Capacitance = ?
Tolerance = +/- 20%

Convert Values to Codes:


Code = ?
Tolerance Code = M
