negative pole. When it is connected “the wrong way around” over a longer
period, the electrolyte of the capacitor will be destroyed.
Do not exceed the imprinted maximum voltage indication, because
otherwise the insulation layer can be destroyed.
Enclosed you find radial electrolytic capacitors with the following
capacities: 1000µF and 4700µF

with connecting wires. The
positive pole is the longer
connection wire. In addition the
negative pole is designated with
a bright line on the enclosure.
For simplicity, the term “electrolytic capacitor” is sometimes shortened to
“electrolytic”. This abbreviation is mainly used in the US.
