POWER RATING CHART TEMPERATURE RISE
PRACTICAL OPERATING TOLERANCES
After 1000 hours 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 Ω), tolerance (in %), temperature coefficient, manufacturing
date. Due to lack of space RCMX02 is printed MX02.
