hello
I have found this post http://forum.allaboutcircuits.com/showthread.php?t=21083&highlight=capacitor+irms but it ends with the same question that I have.
I am using the LM2679 datasheet to a project http://forum.allaboutcircuits.com/showthread.php?t=89463 , on the page 20 it mentions that the capacitor Nichicon PL series with 560uF and WV of 35volts has a IRMS of 1.43Amps.. I have found out that Nichicon PM series is the old PL series, and went to download the datasheet(e-pm-29711.pdf), it mentions the following :
the capacitor with 15x16mm form factor has a a impediance of 0,040 ohms at 20ºC and 100Khz, it has a ripple current of 1.1 ARMS at 120hz.
What is the IRMS of this capacitor, if I go for I = V / R, I get 35/0.04, wich is 875 amps, wich is wrong.. please educate me
