Electrolytic Capacitors
Electrolytic capacitors are used as input buffers to supply ener-gy when the mains input voltage is too low, store energy while an AC/DC converter adapts to a new power level, and prevent switching noise from the converter reaching the power source. On the output of a converter, they act as a filter and current sink for inductive elements, and, in DC/DC conversion, function as an …

Mechanically damaged aluminium electrolyte capacitor
$begingroup$ The electrolyte is not very toxic, but it will make you sick if you swallow enough of it. If you just touched a small amount of it you should have no reason to worry. At room temperature, there would not be much vapor. A capacitor that overheats in a live circuit will release some vapor. I have seen large capacitors overheat and ...
