[REV5 notes in brackets]

NOTE: Non-Polarized (NP) Electrolytic capacitors and small ceramic capacitors 
can be installed without regard to physical orientation.

NOTE: Leads may need to be straightened to allow the capacitor to sit down onto 
the circuit boards surface. 

NOTE: Observe polarity on C6 and C12 where the long lead is positive and inserts
into the "square" hole.

C1 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C2 - (105) 1uF ceramic (yellow)
C3 - (103) .01uF .2LS (yellow or blue)
C4 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C5 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C6 - 10uF 16V - 25V 5mm polarized Electrolytic
C7 - (104) .1uF .2LS (yellow)
C8 - (103) .01uF .2LS (yellow or blue)
C9 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C10 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C11 - (104) .1uF .2LS (yellow)
C12 - 10uF 16V - 25V 5mm Electrolytic
C13 - 10uF NP (SMT) [leaded non-polarized Electrolytic]
C14 - 10uF NP (SMT) [leaded non-polarized Electrolytic]


NOTE: Install the shorter part of the header into the circuit board, allowing the 
longer part of the pins sticking out so the shorting bar can be installed.
