Pulse Duration
(ms)
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.
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.
