Background: I was looking at a spec sheet for a round metallized polypropylene film capacitor that gave two different current values for the "IRMS at 100 kHz -70 deg C" and the "Peak Current"
I'm planning on using a pulsed power system that produces 300 A pulses that last for 27 uS and occur at a frequency of 10 Hz. The IRMS at 100 kHz given was only 13.5 A, while the peak current was 432 A.
Question: What's the difference between the two? Based on the specs given, will the capacitor likely be able to handle the 300 A pulse I described?
