Electrolytic capacitors (elcos) have a high capacity as compared to regular capaci-

tors. Due to the electrolyte, an electrolytic capacitor is polarity-dependent and the 

connections are marked with a plus and a minus pole. If a component is connected 

»swapped« for an extended period of time, this will destroy the electrolyte of the 

capacitor. The printed-on maximum voltage indication should not be exceeded. 

Else, the insulation layer may be destroyed.

µ always is the millionth part of the basic unit. µF means micro farad.
