Capacitor code calculator

Small ceramic capacitors print a 3-digit code instead of a value. The first two digits are significant figures and the third is the number of zeros, giving a value in picofarads: a code of 104 means 10 × 10⁴ = 100 000 pF = 0.1 µF.

Enter the code and tolerance letter to read the capacitance in pF, nF and µF — all computed in your browser, nothing uploaded.
