The colors on the color ring inductor mainly represent numbers, magnification and error levels, as follows:
-Black: stands for 0.
-Brown: stands for 1.
-Red: for 2.
-orange: for 3.
-Yellow: for 4.
-Green: for 5.
-Blue: 6.
-Purple: 7.
-Gray: 8.
-White: 9.
-Gold: it means multiplying by 0.1 (10^-1).
-Silver: it means multiplying by 0.01 (10^-2).
-Black: it means multiplying by 1 (10^ 0).
-Brown: it means multiplying by 10 (10 ^1).
-Red: it means multiplying by 100 (10^ 2).
-orange: it means multiplying by 1k (10^ 3).
-Yellow: it means multiplying by 10k (10^ 4).
-Green: it means multiplying by 100k(10^5).
-Blue: it means multiplying by 1m (10^ 6).
-Purple: it means multiplying by 10m (10^ 7).
-Gray: it means multiplying by 100M(10^8).
-White: it means multiplying by 1000M(10^9).
-Gold: indicates an error of 5%.
-Silver: indicates that the error is 10%.
-Brown: indicates that the error is 1%.
-Red: indicates that the error is 2%.
-Green: indicates that the error is 0.5%.
-Blue: indicates that the error is 0.25%.
-Purple: indicates that the error is 0.1%.
-Gray: indicates that the error is 0.05%.
-Colorless: it means that the error is 20%.
For example, if the color sequence of a color ring inductor is brown, black, orange and gold, its inductance value is 10× 10 3 = 10,000 NH, that is, 10 μH, and the error level is 5%.
