Resistor identification

Okay, this may be the most newb question I will ever ask! I am just about to start sourcing parts for my second build and have come up against something I didn't encounter in the first.

When resistors are identified with an "R" instead of a "K" or "M", does that mean the values should only be in ohms as opposed to K ohms or M ohms? In other words, would 470R mean 470 ohms? I've only ordered from Small Bear and Mammoth, but they don't list them with the "R".

Thanks to anyone who can point me in the right direction here!

Yep.  R = Ohms in this context.  That's a good thing to catch early, too.  Mistaking an R for a K is one of the most common mistakes.

Thanks for confirming! I believe you may have saved me from a heap of trouble.

Cheers,

Hi Bret,

I already posted this in a reply to one of your other questions, but it is so good that I'm gonna post it again:

Very helpfull when deciding what resistors to use!

I believe you did! And it was helpful in identifying all those resistors I got from Small Bear! I just hadn't dealt with anything under the k-ohms level during that first build.
