Rated voltage = √Power rating x resistance value or max. working voltage, whichever is lower
*The nominal resistance value for RK73H1F (F:±1%) is E24
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 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.

Terminal Part Temperature
(°C)
For resistors operated at an ambient temperature of 70°C
or above, a power rating shall be derated in accordance
with the above 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 above
derating curve.
Please refer to “Introduction of the derating curve based
on the terminal part temperature” in the beginning of our
catalog before use.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
