### How to read a capacitor value?

The first two colors indicate significant digits of the value of the capacity (in pF), the next color is the corresponding power of 10, the other two colors are optional and indicate tolerance and maximum voltage.

 Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Grey 8 White 9 Gold -1 Silver -2

Consider a capacitor [Red, Blue, Orange, Green]

Recover the corresponding values for colors

Red = 2, Blue = 6, Orange = 3, Green = 5

Make the calculation $$( [Color1] * 10 + [Color2] ) * 10 ^ {[Color3]} ± [Color4]% (Tolerance)$$

26 x10^3 ± 5% = 26000 pF ± 5% = 26 nF ± 5%

### What is the unit for capacitors?

The capacitors have capacities expressed in Farad. In practice sub-multiples are used:
1 F = 1000 mF (milli Farad)
1 mF = 1000 µF ou uF (micro Farad)
1 µF = 1000 nF (nano Farad)
1 nF = 1000 pF (pico Farad)

### How to read the value of a 3-digit capacitor?

Sometimes the capacitor value is indicated with 3 digits. As for colors, the first 2 are significant digits, and the third is the power of 10.

123 => 12 x10^3 => 12 nF
