High Precision Resistors (SMD)
Type RN73 Series
Type RN73 Series
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
sputtered
produced
layers
with
giving
three
the E96 and E24 value grids. The
RN73 has accurate and uniform
dimensions
