[sdiy] Need help with a SMD kit (OT?)

[David Moylan]

I was thinking more in terms of noise as, at least in through hole, 
larger wattage of the same resistor seem to exhibit less noise.   The 
datasheet says low noise but doesn't give any spec.

The RG3216 is 1206 (imperial) package and 1/2W.  Now my only complaint 
is price.  9.1 cents in quantity as opposed to 1.4 cents in through hole 
at Mouser.  RG2012 series 0805, 1/8W are a little cheaper.  These are 
also .5% tolerance, so a little tighter than the 1% through hole.

Probably worth a try.

There are some cheaper thin films ones from Yageo but no noise specs and 
no mention of resistive material either.
