High long term stability drift < 0.25 % after 1000 h
The performance of the RCMT resistors exceed the
requirements of NF C 83-230 standards. They are
particularly relevant to the more stringent military and
industrial applications especially when high ambient
temperatures such as + 175 °C are to be encountered.
The RCMT resistors are qualified and released to the
NF C UTE 83-230 standard styles RS56C, RS60E and C,
RS65E and C, RS70E and C.

NOISE LEVEL
In a frequency decade, the average noise level is 0.1 µV/V
for models RCMT08, RCMT1, RCMT2 and RCMT4 in all
ohmic values. It progressively increases as a function of the
ohmic value and can reach 0.2 µV/V for the highest values of
models RCMT02 and RCMT05 (0.1 µV/V for R < 10 kΩ).
RECOMMENDATION
The lower the ohmic value, the more important the influence
of lead resistance is on measurements. The nominal
resistance value is therefore measured at a distance of 5 mm
from resistor body.
MARKING
SPECIAL APPLICATIONS
Temperature coefficient tracking to 5 ppm.
Tolerance matching to 0.05 %.
Selection of positive or negative TCR in temperature range
of - 20 °C to + 125 °C.
