need to id an inductor..its marked up 220..

i should know this but my minds gone blank...how does the coding go??
obviously first 2 digits are the value and last multiplyer so to speak..so
22 what..nh?uh? etc

thanks..

22 pico-henries? A 220 cap would be a 22 pico-farad. Sorry, my advise would
be measure. And you are right, we both should know this.

Flippin' 'eck! 22pH is probably less than the stray inductance of the
device itself!
Actually, I can never rememeber these codings either. I believe it's
22uH but if someone more knowledgable can post the key to the inductor
multipliers here it would be very helpful!

Hi all

But red/red/black should be 22 micro Henry's , shouldn't it ?

220 is red-red-brown, usually, but you never know which standard they
follow, or perhaps they have their own standard, so even when they
write figures 220 could mean 22 or 220 µH, and pF if it was a
capacitor....
