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.
