POWER RATING
TEMPERATURE RISE
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.
Thus, in operation under the specified conditions (P
r
at
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���
values. It is non measurable for R
n
< 2 k.
MARKING
Printed: Vishay Sfernice trademark, series, style NF style (if
applicable), ohmic value (in ), tolerance (in %), temperature
coefficient, manufacturing data. Due to lack of space RCMS
02 is printed MS 02.
