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

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.
