Ratings
Power derating curve
・For resistors operated in ambient rated ambient temperature, power rating shall be derated in accordance
with the figure below.
In addition, please use under the condition that the product temperature is below the upper category
temperature.
※ When the temperature of ERJP14 is 155 ℃ or less, the derating start temperature can be
changed to 125 ℃. (See the dotted line)
・For resistors operated in ambient rated terminal part temperature, power rating shall be derated
in accordance with the figure below.
In addition, please use under the condition that the product temperature is below the upper category
temperature.
