These capacitors are necessary to accommodate our test equipment and may
not be required to achieve specifi ed performance in your applications. All models

tolerate brief full current outputs if the total RMS current over time does not exceed
the Derating curve. All Derating curves are presented at sea level altitude. Be aware
of reduced power dissipation with increasing density altitude.
