The RN73 ser ies is a stable precision chip resistor range
offering various power dissipation relating to chip size,
TCR's down to 10ppm/°C and resistor tolerances to 0.1%.
The resistor is pr oduced with thr ee sputter ed la y ers giving
better perfor mance. Values are restricted to the E96 g r id
and the RN73 has accurate and uniform physical dimen-
sions to facilitate placement. They are of course packaged
on tape and reeled.
