Type RN73 Series
The RN73 series is a high stability precision chip resistor range offering
various power dissipations relating to chip size, TCR's down to 5ppm/°C
and resistance tolerances to 0.01%. The resistor is produced with three
sputtered layers giving optimum performance. Values are restricted to
the E96 and E24 value grids. The RN73 has accurate and uniform
physical dimensions to facilitate placement.

Handling Recommendations
When flow soldering - the land width must be smaller than the Chip Resistor
width to properly control the solder application. Generally, the land width
can be Chip Resistor width (W) x 0.7 to 0.8. When reflow soldering – solder
application amount can be adjusted. Thus the land width can be set to W x
1.0 to 1.3.
