Derating Curve (Ambient Temperature)
For resistors operated at an ambient temperature of 85C or above, a power rating shall be derated in accordance with the derating curve.
Note: Please refer to Introduction of the derating curve based on the terminal part temperature in the beginning of our catalog before use. If any questions arise whether to use the Rated Ambient Temperature or the Rated Terminal Part Temperature, please give priority to the Rated Terminal Part Temperature.
Packaging Information
Packaging options include TD (4mm pitch punched paper) and TPL-TP (2mm pitch punched paper). For further information on packaging, please refer to Appendix A.
*1 Measurement Temperature: +25C/+125C. Cold T.C.R. (-55C/+25C) is -50~+25x10-6/K
