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.
