They are about US$4 for 10 pieces at Digikey, not the end of the world
unless John is going into production. (2010 and 2512 1/2 and 1W
Panasonic parts). Unfortunately, the data sheet doesn't show the
inductance, but for SMT resistors, it's usually quoted as a low number
These things (at low resistance anyhow) are usually a flat sheet of
resistive material with an "L" shaped kerf in them from trimming, so
there shouldn't be much inductance.
