RF Inductors – Color Coding

xx145RAN (0201), xx220RAA (0302), xx235xxx (0402) and
xx256RAD (0403)

Because of their small size parts smaller than 0603 are not marked.


xx312xxx (0603), xx336xxx (0805) and
xx413xxx (1008)

0603, 0805 and some 1008 size parts are marked with a single color dot. The inductance value  represented by the dot is shown on the data page for each series The dot is for identification only and does not indicate polarity.


xx413xxx (1008), xx376RAA (1206) and
xx450xxx (1812)

Some 1008 size parts are marked with one dot. The inductance value represented by the dot is shown on the data sheet for the series. The dot is for identification only and does not indicate polarity. Other parts are marked with three color dots. The dots do not indicate polarity.

Dots 1 and 2 indicate the inductance in nanoHenries.

Dot 3 is a multiplier equal to 10dot 3

Examples:
Gray, Red, Black = 82 × 100 = 82 nH
Brown, Red, Brown = 12 × 101 = 120 nH
Yellow, Violet, Red = 47 × 102 = 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.
