Specific marking codes apply for different sizes, tolerances, and resistance values (e.g., 3-digit for standard values, 4-digit for E96 values, alpha-numeric for 0603, 1%). Sizes 01005, 0201, and 0402 cannot be marked.
A derating curve is provided illustrating rated power percentage versus ambient temperature for different size groups.
