Characteristics - Electrical
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.
