The first step to finding a cross is identifying the bad capacitor, and correctly reading the specifications printed on the top or side of the capacitor. Most, if not all, will have the capacitance, voltage, some sort of manufacturer marking, and a designator for the negative lead/pad if polarized.
The RMS current rating of a capacitor is determined by the amount of current required to raise the internal temperature approximately 10°C above an ambient temperature of 105°C. This is NOT the value you want to use in the design, rather the max rated for which capacitors are rated for often 1500 hrs lifespan at the rated temperature.
Voltage breakdown is a test method used to quantify the voltage level strength of a capacitor. DC voltage is applied across the capacitor at a fixed voltage ramp rate (i.e. 100v/s) until the part fails. This determines the maximum sustained voltage the capacitor can withstand but does not directly indicate maximum ESD voltage level.
The other issue is the frequency response which brings me to the next point, calculating the capacitor values. Capacitors. So I understand that C1 must be chosen based on the low frequency cutoff. I have chosen the low frequency cutoff to be 20Hz (arbitrarily). Using the following formula:

Re: Finding low-ESR 400V capacitors Aha! I didn''t think of that. So the high frequency/high ripple part of a switching mode PSU basically comes after the first transformer, and that''s where you need low-ESR caps because otherwise their internal resistance will drop the voltage output and also generate internal heat which will in turn …
