Vishay Sfernice
Molded Metal Film High Stability (< 0.25 % after 1000 h)
High Temperature (up to 175 °C) Precision Resistors
FEATURES
•
0.1 W to 2 W at 125 °C
•
EN 140-100
•
CECC 40 101-044
•
High climatic performance - 65 °C/+ 175 °C/56 days
•
High long term stability drift < 0.25 % after 1000 h

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).
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.
For these applications and other requirements consult VISHAY SFERNICE.
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.
