SELECTING CAPACITORS:

Size and shape as well as electrical characteristics must be considered if it is to fit into the available space.
AXIAL capacitors are the same shape as resistors with a wire coming out of each end.
RADIAL ones have both leads coming out of the same end.
Make sure it has the correct lead spacing.
Ensure that the circuit voltages do not exceed the capacitors maximum working voltage.
Electrolytic and tantalum capacitors are polarised and must be fitted the correct way round.
