✽ Please contact us when resistors of irregular series are needed.
<Supplemented>
In the case of the temperature measurement of the terminal portion of
the resistor, Please perform under the following conditions.
1) Tarminal 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.
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.
