Derating Curve
The derating curve illustrates the reduction in rated power as ambient temperature increases. For 01005 & 0201 sizes, derating starts from 70C. For 0402 to 2512 sizes, derating starts from 70C, with full power capability up to 70C and reduced power at higher temperatures.
Marking Code
Marking depends on size, tolerance, and resistance value. Smaller sizes (01005, 0201, 0402) cannot be marked. Larger sizes may use 3-digit or 4-digit codes for standard resistance values and tolerances. E96 values utilize a two-digit code combined with a letter multiplier for precise marking.
