✽ Please contact us when resistors of irregular series are needed.
Power derating curve
If the terminal temperature of the resistor is more
than terminal temperature upper limit value of the
rated table, please reduce the rated power according
to the Power Derating Curve shown in the figure on the right.
＜Supplemented＞
In the case of the temperature measurement of the terminal portion of
the resistor, Please perform under the following conditions.
1）Terminal temperature measurement, please apply the temperature of
the higher of either the left or right electrode upper surface of the resistor.
2）Please measure the temperature of the resistor in the land pattern
printed of circuit board and plan to use by real conditions.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
