0201, 0302, 0402 and 0403 Series

Because of their small size, 0201, 0302, 0402 and 0403 parts are not marked.


0603 and 0805 Series

0603 and 0805 parts are marked with a single color dot. The inductance value  represented by the dot is shown on the data page for each series.


All 1008, 1206, 1812 and Midi Spring Series

These parts are marked with 3 color dots. The table at right   shows the significance of each color.

Dots 1 and 2 indicate the inductance in nanoHenries.

Dot 3 indicates the number of zeroes to be added.

Examples:
Gray Red Black = 82 nH
Brown Red Brown = 120 nH
Yellow, Violet, Red = 4700 nH

Values below 10 nH

On these parts, the third dot is not a multiplier. Refer to the table below for the specific inductance values represented by the color dots.
