Operating Temp: -55C to +125C (SR731H only), -55C to +150C If any questions should arise whether to use the "Rated Ambient Temperature" or the "Rated Terminal Part Temperature," please give priority to the "Rated Terminal Part Temperature." Prior to use and for more details refer to "Introduction of the derating curves on the terminal part temperature" in the beginning of the catalog. 1 Prior to use, refer to the "Higher Power Ratings" in the beginning of catalog. Rated voltage = Power rating x resistance value or max. working voltage, whichever is lower environmental applications Derating Curve SR73 2A (0.5W), SR73 2B (0.5W), SR73 2E (0.66W) 1E, 1J 2A: 0.33W 2B: 0.33W 2E: 0.5W W2H, W3A For resistors operated at an ambient temperature of 70C or above, a power rating shall be derated in accordance with the derating curve. For resistors operated at a terminal part temperature of described for each size or above, a power rating shall be derated in accordance with the derating curve. Please refer to "Introduction of the derating curve based on the terminal part temperature" on the beginning of our catalog before use. Performance Characteristics Parameter Resistance T.C.R.
