☑ Color Coded Inductor

1st band silver military inductor indicator 2nd band red 2 3rd band violet 7 4th band brown 1 or 10 5th band gold 5 tolerance thus the inductor value is 270 uh 5. The table below shows the significance of each color.

Other parts are marked with three color dots.

Color coded inductor. The color codes for inductors are identical to that of a resistor so if you are familiar with resistors this should be very easy. 1 1 1 1 1 rating 358 12 votes color coil. In such cases the silver dot indicating a military mil specification will be larger than the other dots and will be placed a the beginning of the dot sequence.

Dot 3 indicates the number of zeroes to be added. The dots do not indicate polarity. The inductance will be shown in the box above the image along with the units and tolerance.

If the first or second band is gold this represents the decimal point for inductance values less than ten. In the above figure inductor consists of following colors. Repeat for all bands tolerance is optional.

To convert from colours to value. Hover the mouse over the coloured bands on the image of the inductor to display the colour selector box then click on the required colour. Standards iec 60062 en 60062 do not define a color code for inductors but various manufacturers which of physically small inductors utilize the resistor color code for this purpose typically encoding inductance in microhenries.

Then the following two bands significant figures. Dots 1 and 2 indicate the inductance in nanohenries. For inductors of a very small physical size coloured dots may be used instead of bands.

Select quantity of bands. A white tolerance ring may weasel words indicate custom specifications. Inductance of color coded inductors 36 out of 5 based on 12 votes.

Smaller inductors use numbers instead of colors you can find more about these here. For inductance values of 10 or more the first two bands represent significant figures and the third is the multiplier. 3 bands short standard 4bands common standard.

Values below 10 nh. Inductors can be marked by colored bands or colored dots. Easily determine the inductance of color coded inductors see more.

5 band inductor color code example for the values equal or higher than 10 uh. Inductors can have four or five bands. The tricky part is remembering the results from this will be in microhenrys not just henrys.

Color coding is in accordance with the color code table shown right. Gray red black 82 nh brown red brown 120 nh yellow violet red 4700 nh. Inductor color code the inductance of an inductor can be calculated with the colors of the bands.

Each color represents a value. First break down the bands.
