This topic is getting a bit heated - time to drop it I think.
Although it is always tempting to get the last word in on a topic this one
seems to be getting personal and we don't really need that do we. Maybe it
could go to the OT list, or better still to private email.
My opinions only of
http://www.garrettelec.com/ supplies small quantities of surface mount
parts. You can check stock online.

Juha,
Have you
considered doing your resistance as a short section of PCB trace? For
example a 0.020 wide trace, 1 oz CU, of 0.161 inches in length will give
you a resistance of 0.00399 ohms according to some calculators. This length

Hi,
Looking for 0.004R (2512 footprint, 1-2W) sense resistor for switching power
supply, can you help me?
I have one (IRC LRF 2512-01-R004-J http

This may or may not be a bad thing, the magnetics have tempcos too. I'd
avoid it just because some day in the future someone will buy 2oz boards
rather than 1 oz.

but
distributor says that you have to get 1800 (I need 100-200), you know
where
prob. need a slider type
ohmite, they break real easy though and their mounting clips suck
newark should have them, they only charge about 25% more than list price
great recommendation, eh?,
but seriously at that exact value i think it will be tough
dale does those ones with a gold color heat
