• NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
For schematic diagrams.
Note:
• 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

W or less unless otherwise
specified.
•
f
: internal component.
•
C
: panel designation.
For printed wiring boards.
Note:
•

).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
