This batch of capacitors are called electrolytic capacitors. They are polar-
ized with a (+) and (-) lead and must be installed in the correct orientation.
Ordinarily, only the negative side is marked on the capacitor body with a dark
band and the (-) sign clearly shown, while the PC board has a “+” printed
next to the pattern indicating the “+” lead. Be careful and install the ca-
pacitors with the negative lead in the opposite hole from where the “+”
is indicated on the board. Failure to do so may result in the capacitor actu-
ally
EXPLODING and causing possible damage to you and/or the board.
In addition to the capacitance and polarity markings you will also find a volt-
age indication. Any value greater than 16 volts is good for our application.
The capacitors should fit snugly down on the PC board.
