※1 If you use at the rated power, please keep the condition that the terminal of the resistor is below the rated terminal part temperature. Please refer to the derating curves based on the terminal
temperature of right side on the next page.
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
Temperatu r e ”.
For more details, please refer to“Introduction of the derating curves based on the terminal part temperature”on the beginning of our catalog.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
Contact our sales representatives before you use our products for applications including automotives, medical equipment and aerospace equipment.
Malfunction or failure of the products in such applications may cause loss of human life or serious damage.
