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” in the beginning of our catalog before use.

The maximum applicable voltage is
equal to the max. overload voltage.
Please ask us about the resistance
characteristic of continuous applied
pulse.
The pulse endurance values are
not assured values,so be sure to
check the products on actual
equipment when you use them.

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. Please refer to
us before use.

The temperature of the resistor will
increase the same ⊿T from the
standard terminal part temperature
regardlless of the ambient temperature
when the same power is applied. This
is because there is hardly any heat
dissipation from the resistor surface
to the ambient air.
