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. 2 applications and ratings (continued) RK73Z Part Designation Rated Ambient Temperature Rated Terminal Part Temperature 1H (0201) 1E (0402) 1J (0603) 2A (0805) 2B (1206) 2E (1210) W2H (2010) +70°C Resistance Current Rating Maximum Surge Current 100mΩ max. 0.5A 1A 1A 2A 5A +125°C 50mΩ max. 2A Operating Temperature Range -55°C to +155°C 10A W3A (2512) Specifications given herein may be changed at any time without prior notice.
