Default Re: PSU11/Phono11 - voltage drop

I know, I could find stuff easy on the old RS site, now its a pain. Especially if you are trying to pick a part on spec, on the old site, like the catalogs, semiconductors were in a nice easy chart with all the important numbers on view.

39k2 167-298

You are right about the 316K though, odd, its in the series. Farnell have them both with the 316k the 0.5% range. Maybe thats why they are not to be found at RS.

39k2 340704
316k 640992

Cheers Nick,
Buddam is going to be putting an order into M Percy, they do Roderstein metal film 1/2W, 1%. They have both the values required and are only 25 cents each. Percy also do the Caddock MK-132, which apparently are guaranteed not to drift more than 1% of the value in their life but they only have 316K and they cost $4.50 each.
