The three types of capacitors shown below are polarized and have to be installed in the
correct orientation. Note the stripe running the length of each cap; this identies the
negative (minus) lead. On the circuit board, the circle for this cap’s location has a round
through hole on one side, and a square through hole on the other: insert the capacitors
with their stripe facing the round hole side. (On polarized caps of this type, there’s a
second way to identify the negative lead: it is the shorter of the two leads).
