PRACTICAL OPERATING TOLERANCES

Tables 2 and 3 show the basic characteristics and max.

values under different stresses. In fact, the values and drifts

are maintained to within narrower limits.



70 °C) the total drift (load life + TCR) of a RCMS K3 does not

exceed ± 0.5 %.

NOISE LEVEL

In a frequency decade, the average noise level increases

with the ohmic value and can reach 0.3 μV/V for the highest



MARKING

Printed: Vishay Sfernice trademark, series, style NF style (if

applicable), ohmic value (in
