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

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 Francesco

the
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.
