Juha,
seems you are looking for a highly specialized part. 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
would probably need to be tweaked according to you PCB specs and the
fabricators typical tolerances. A lot of current sense devices have
application notes which suggest using specific lengths of traces for your
sense circuit.
Sincerely,
Brad Velander.

Subject: [PEDA] Looking for a resistor supplier.
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://www.welwyn-tt.com/lrc_fr.htm ) but
distributor says that you have to get 1800 (I need 100-200), you know where
can get less?
Sincerely,
