* 1F: E-24. 1H: 1.0~9.1, 1M~10MΩ: E-24. 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.” Prior to use and for more
details refer to “Introduction of the derating curves based on 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.
