Should ventless electrolytic capacitors be mounted upside down?
I read in this CDE application guide and this Nichicon application guide that if a screw terminal electrolytic capacitor is installed upside-down, the vent may not function properly and the electrolyte may leak out. Proper orientation is upright, or horizontal with the vent at the top of the capacitor. Smaller electrolytic capacitors often do not have such a vent, …
