More specifically, do these matter when picking caps for general arcade hardware; I know it can matter in certain electronics applications.
I typically by cap kits from an arcade parts seller, or bulk caps from Digikey/Mouser. I never look much past buying Nichicon, 105C, and then matching compacitance and matching/exceeding voltage. Sometimes I'll look or specific physical sizes when I know the area is tight on the PCB.
Is there ever a reason to look at impedance or ripple current as well?
