Color coding of the inductance value
The inductance value and tolerance are encoded by means of colored bands in accordance with
IEC 60062. The basic unit is μH.
1st band 1st digit of inductance value
2nd band 2nd digit of inductance value
3rd band multiplier, i.e. the power of ten, by which the first two digits have to be multiplied.
4th band tolerance of the inductance value.
Color code
1st band =
