Electrolytic Capacitors
The remaining capacitors are electrolytic types.
Unlike the previous components, electrolytic
capacitors are polarized and the leads are not
interchangeable. Leads are marked "+" and/or "-"
and the "+" lead must go through the "+" hole in the
circuit board. Frequently the positive lead of the
capacitor is significantly longer than the negative lead.
Usually the Negative lead of the capacitor is marked rather
than the positive. It naturally goes through the unmarked hole.
Capacitors supplied with specific kits may have a higher
Voltage (V) rating than the minimum specified below.

Diodes
Like the Electrolytic Capacitors, diodes are polarized
and must be installed so that the lead on the banded
end of the part corresponds to the banded end of the
designator on the circuit board. Bend the leads so they
are at right angles to the body of the part and insert
them through the holes provided in the circuit board.
Diodes are also somewhat heat sensitive so the
soldering operation should be done as quickly as possible.
