Microfarads to capacitor code

Type a value in µF to get it in code instantly.

478code

That's 4.7× as large as a 1,000 µF reservoir capacitor — nothing on our list beats it.

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 µF to code

pF = first two digits × 10^third digit: 104 = 10 × 10⁴ pF = 100 nF; 4R7 = 4.7 pF.

Example: 4,700 µF = 478 code.
