Pulse limiting voltage (current, wattage) is applied at less than rated ambient temperature.
If ambient temperature is more than the rated temperature (70 °C), decrease power rating according to
“Power Derating Curve”
Assure sufficient margin for use period and conditions for “pulse limiting voltage”
If the pulse waveform is not square wave, judge after transform the waveform into square
wave according to the “Waveform Transformation to Square Wave”.

Dimension "E":
This is a non-critical dimension that does not have a tolerance in the standard.
Range of diameters is from 0.547 inches (13.90 mm) to 1.500 inches (38.10 mm).
(1) Reference value only. The "A" dimension shall be governed by the overall length of the taped component.
The distance between flanges shall be 0.059 inches (1.50 mm) to 0.315 (8.00 mm) greater than the overall component.
(2) The given dimension "D" expresses the standard width spacing. A 26 mm narrow spacing is available as option "N" packaging code.
