PRACTICAL OPERATING TOLERANCES
After 1000 h load life at rated power 90'/30' cycles +70 °C
ambient temperature, the typical total drifts, measured at
+70 °C, are as follows:
Typical total drift = drift due to TCR (K3) + life drift 0.5 %.
Maximum deviation from rated ohmic value including ± 1 %
manufacturing tolerance
1.5 %.
MARKING
Printed: Vishay Sfernice trademark, series, style, ohmic
value (in
),
tolerance (in %), temperature coefficient,
manufacturing date. Due to lack of space RCMX02 is
printed MX02.
