Hello there everybody!!

I have a radial inductor whose color codes I cannot read. Reading from left to right-Black(big dot)-Black(small dot)-gold(small dot)-Gold(big dot). So what is its inductance??Can you suggest an online calculator for this??

Thanks for answering!!

The big dots i mentioned are in the sides. The small dots are in top. Sorry, the small dot is violet and yellow, not black and gold.

Violet and yellow is a standard pair for "47" and if the only other dot is black, I would assume that is the multiplier, so you have 47 + 0 tens or 47uH.
