The numbers represented by the colors of the color ring inductance: brown 1, red 2, orange 3, yellow 4, green 5, blue 6, purple 7, gray 8, white 9, black 0
The magnification represented by the colors of the color ring inductance: brown * 10 (10 ^ 1), red * 100 (10 ^ 2), orange * 1K (10 ^ 3), yellow * 10K (10 ^ 4), green * 100K (10 ^ 5), blue * 1M (10 ^ 6), purple * 10M (10 ^ 7), gray * 100M (10 ^ 8), white * 1000M (10 ^ 9), black * 1 (10 ^ 0), gold * 0.1 (10 ^ 1), silver 0.01 (10 ^ 2)

The error levels represented by the color ring inductance colors are: gold 5 [%], silver 10 [%], brown 1 [%], red 2 [%], green 0.5 [%], blue 0.25 [%], purple 0.1 [%], gray 0.05 [%], colorless
The basic unit of color ring inductance is "micro Heng"

Taking the four ring inductor as an example:
Reading method of four loop inductance: the first two digits are Significant figures, the third digit is magnification, and the fourth digit is error level.

For example:
First Ring: Brown - represents 1
Second Ring: Black - represents 0
The third ring: red represents two zeros, but the "2" in the third ring is not "Significant figures", but the number of "zeros" added after the first two Significant figures.

From this perspective, the inductance of this inductor should be 1000, in what units? In the color ring inductance, it is always defaulted to "micro enjoyment" (the basic unit of inductance, with the symbol uH).
The inductance value of the above inductance is: 1000uH (102)

So, what does the fourth ring mean? The fourth ring represents the "accuracy" of the inductance, which is the error of the inductance value. Gold represents an error of ± 5%, while silver represents an error of ± 10%.
