color code on radial inductors
 

Hello,
does anyone know exactly how to read the color code on radial through
hole inductors? They have two small color dots on top and one or two
big dots on sides. I tried to search on the internet but seems like
all internet color codes are for well known axial (resistor-like)
inductors.

Thanks in advance
Francesco

If they are like this
2 large - Gold, Brown
2 small - brown,black placed in that order between gold and black it means
100uH, gold presumably means tolerance or just an identifier but its on the
left hand side of reading the dots, unlike resistor bands.

At least on pale blue cased globular ones it is

I will add to my tips files , URL below

What are the colours on yours ?

I chose a bad example
gold,orange,orange, black
means 33 uHenry

gold,brown,green,brown
means 150uH

For physically larger ones (again light blue body) with 3 dots only , read
from the top and multiplier nearest a pin. eg
brown,black,red = 1000 uH , not 200uH

yes, pale blue globular.
The gold side dot isn't always present. So the lateral dot is the
multiplier?

Thanks

For the 4 dot ones, the 2 small dots on the top, farthest from the pins, and
the large dots on the sides. So presumably a small 3 dot one, with one large
dot on its own, is the multiplier.
