Capacitor code to microfarads
Type a value in code to get it in µF instantly.
0.0047µF
That's about the same as a 4.7 nF filter capacitor.
Convert the other way: µF to code
What it means
How big is that capacitor?
A letter after the code is the tolerance (J 5 %, K 10 %, M 20 %, Z +80/−20 %) and is ignored. Electrolytic capacitors print their value in µF directly.
The math
How to convert code to µF
pF = first two digits × 10^third digit: 104 = 10 × 10⁴ pF = 100 nF; 4R7 = 4.7 pF.
Example: 472 code = 0.0047 µF.
