Starting near the center left hand side of the PCB:
C5 0.1 uF (104)
C8 0.1 uF (104)
C3 0.1 uF (104)
C4 0.1 uF (104)
Starting near the lower left hand side of the PCB:
C12 (skip for now)
C9 0.01 uF (103)
C13 0.01 uF (103)
C6 33 pF (33 or 330 - NOT the large, rectangular capacitor that may be marked 330n)
In the following step, pay particular attention to ensure that the leads of C7 do not extend below the bottom
of the PC board. You may find it easiest to pre-trim the leads before you solder.
C7 0.01 uF (103)
You should have one 470 pF ceramic monolithic capacitor remaining, and location C12 should be
empty.
The following capacitors are polarized. This means that it matters which lead goes into which hole on the
PCB! Take a moment to examine the electrolytic capacitors supplied. The positive (+) lead is typically
longer than the other. In addition, the negative lead side is usually marked on the case with a bold stripe.
Be sure you know which lead is the positive lead.
On the PCB, the positive lead has a square pad, and is marked with a + symbol.
There are two physical sizes of 10 uF capacitor supplied. One is much smaller than the other.
Use the small capacitors in the following two steps.
Near the bottom center of the PCB:
C10 10 uF low profile capacitor (10 uF or 106)
C14 10 uF low profile capacitor (10 uF or 106)
