Hi all

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

Try 220 Micro Henry's :-)

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.

Most likely 22 micro Henries or possibly 220 micro Henries.

It is 22uh

Look it as if it was a resistor but instead of ohms you express it in microhenrys

Red red black is 22ohms so your inductor is 22uh

The multipliers are
Brown 10
Black 1
Gold 0.1
Silver 0.01

So if the colors was red red gold then it would be 2.2uh and so on

It took me weeks to realize that I was reading an 22uh inductor as 220uh
