Decode the 3-digit code printed on ceramic capacitors into picofarads, nanofarads and microfarads. Includes the tolerance letter.
The first two digits are significant figures and the third is the number of zeros (the multiplier), giving a value in picofarads. So 104 means 10 followed by four zeros = 100,000 pF = 100 nF = 0.1 µF. A trailing letter is the tolerance.
The first two digits are the significant figures and the third is how many zeros to add, giving a value in picofarads. For example 223 is 22 followed by three zeros = 22,000 pF = 22 nF.
10 followed by four zeros = 100,000 pF, which is 100 nF or 0.1 µF, one of the most common decoupling capacitor values. This tool converts any code into all three units.
It is the tolerance. Common ones are J for ±5%, K for ±10% and M for ±20%. Smaller tolerances like F (±1%) appear on precision parts.
