I am having trouble verifying the value of an inductor I have. The color bands look like green gold violet silver. My best guess is either 5.7 or 57 Micro henries. Most articles I have seen don't use a gold band as the second identifier. I purchased it a few years ago for a power supply I was building but am now second guessing it value. I know what I hope it is.

 

Do you have an oscope?

 

Not so lucky

 

5.7 uH or 7.5 uH?
