Note for Printed Wiring Boards and Schematic Diagrams
Note on Schematic Diagram:
•
All capacitors are in
µ
F unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
•
All resistors are in
Ω
and
1

4
W or less unless otherwise
specified.
Note on Printed Wiring Board:
•
X
: parts extracted from the component side.
•
Y
: parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.

).
Voltage variations may be noted due to normal produc-
tion tolerances.
