Please refer to the derating curves based on the terminal temperature. If any questions arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature,” in your usage conditions, please give priority to the “Rated Terminal Part Temperature.” Prior to use and for more details refer to “Introduction of the derating curves in the terminal part temperature” in the beginning of the catalog. While using under high power, the temperature of the product may increase depending on the condition of heat dissipation from PCB. Be sure to check the terminal part temperature as well as precautions to use on delivery specification before use. 3 4 Derating Curve 80 1F 1H, 1E, 1J, 2A, 2B, 2E, W2H, W3A (1W), W3A2 (2W) 60 40 20 0 -60 -40 -55 -20 0 20 40 60 80 70 Ambient Temperature (°C) 100 120 140 125 155 For resistors operated at an ambient temperature of 70℃ or higher, the power (for RK73B, RK73H) or a current rating (for RK73Z) shall be derated in accordance with the above derating curve. 100 100 80 80 1H, 1E, 1J, 2A, 2B, 2E, W2H, W3A (1W) 60 40 60 40 20 20 0 -60 -40 -55 % Rated Power 100 RK73B-RK73H-RT Terminal Part Temperature W3A2 RK73B-RK73H-RK73Z-RT Terminal Part Temperature % Rated Power for RK73B, RK73H % Rated Current for RK73Z % Rated Power for RK73B, RK73H % Rated Current for RK73Z RK73B-RK73H-RK73Z-RT Ambient Temperature -20 0 100 120 140 160 125 155 Terminal Part Temperature (°C) 20 40 60 80 0 -60 -40 -55 -20 0 20 40 60 80 100 120 140 160 95 155 Terminal Part Temperature (°C) When the terminal part temperature of the resistor exceeds the rated terminal part temperature shown above, the power shall be derated according to the derating curve.
