POWER RATING CHART TEMPERATURE RISE
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 %.
