Resistors have a low profile, sitting closer 
to the board than taller components, so 
installing these now will make installing 
other parts easier later on.

The 100μF capacitor shown below is polarized and must be installed in the correct 
orientation. Note the stripe running the length of the cap; this identifies the negative (–) 
lead (the negative lead is also shorter).

On the printed circuit board, each capacitor has a square-shaped eyelet marked positive (+). 
The negative lead’s eyelet is round. 

The remaining (3) capacitors below are not 
polarized. However, best practice is to solder 
these caps in place all facing the same direction.
