Thread: Filter Capacitors
face BY : Mark Peterson email (remove spam text)

In many products, I see a large electrolytic capacitor in parallel with a
small disc or dipped capacitor.  Why is that done?  Obviously, the pair
does not act as a single large capacitor, or aonly a single one would be
used.  Just how does that arrangement work?
