I do belive someone (harpo) ...like re "last post" gave you this information !
Ok, sorry, I didn't get it.
Well, I found another post regardin Rp1 and Rp2 by Harpo, explaining them
http://www.groupdiy.com/index.php?topic=4731.msg431566#msg431566
But nothing about power rating.
Isn't Harpo above saying that 1/4W is wrong?
Ok, so I need to consult Ohm?
Well, its: I = V/R
Hm.. where do I get that power rating in, ok.
P = IV >> I = P/V
P/V = V/R >> P = V2/ R
So P = 48V2 / 6081Ohm = 0,379W , right?
So, double that for safety (isn't it so?)
Getting min power rating of 0,758W
Correct?
Changed part to

6,81kOhm, +-0,1, 600mW (best I could find), good choice?
