Document 174 Color Coding Chip Inductors SMD Power Inductors 0201, 0302, 0402, 0403 and 0603 Series Because of their small size, 0201, 0302, 0402, 0403 and some 0603 parts are not marked. Some Coilcraft SMD power inductors are marked with three color dots. The table below shows the significance of each color. 0603, 0805 and 1008 Series 0603 (except 0603AF and 0603CT), all 0805 and some 1008 parts are marked with a single color dot. The inductance value represented by the dot is shown on the data sheet for each series. The dot is for identification only and does not indicate polarity. Identifier or Identifier 1008, 1206 and 1812 Series Some 1008 parts are marked with one dot. The inductance value represented by the dot is shown on the data sheet for each 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. The table below shows the significance of each color. Dots 1 and 2 indicate the inductance in nanoHenries. Dot 3 is a multiplier showing the number of added zeroes 0=Black 1=Brown 2=Red 3=Orange 4=Yellow 1st digit 5=Green 6=Blue 7=Violet 8=Gray 9=White Examples: Yellow Violet Yellow Brown Green Orange Blue Grey Brown 2nd digit Multiplier = = = 470 µH 15 µH 680 nH Dots 1 and 2 indicate the inductance in nanoHenries Dot 3 is a multiplier showing the number of added zeroes 0=Black 1=Brown 2=Red 3=Orange 4=Yellow 5=Green 6=Blue 7=Violet 8=Gray 9=White Examples: Gray Red Black Brown Red Brown Yellow Violet Red = = = 1st 3rd Multiplier 2nd 82 nH 120 nH 4700 nH On values below 10 nH, the third dot is not a multiplier.
