Performance Characteristics
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.
Regarding the temperature rise, the value of the temperature
varies per conditions and board for use since the temperature
is measured under our measuring conditions.
±170°C (2B, 2H, 3AW), 1000 hours
±1.0% + 0.0001Ω––
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 derating curve.
Please refer to “Introduction of the derating
curve based on the terminal part temperature”
on the beginning of our catalog before use.
