Decode ceramic and film capacitor 3-digit codes; convert between pF, nF, and µF
Ceramic and film capacitors use a 3-digit code where the first two digits are significant figures and the third is the power-of-ten multiplier, with the base unit in picofarads (pF). Code 104 = 10 × 10⁴ pF = 100 nF = 0.1 µF.
J = ±5%, K = ±10%, M = ±20%. Voltage codes: A=10V, B=12.5V, C=16V, D=20V, E=25V, F=32V, G=40V, H=50V.
Electrolytic capacitors are marked with value in µF and voltage directly. Ceramic and film SMT parts use the 3-digit pF code because their small size leaves no room for printed values.
