4-2. 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 printed wiring boards.

• Circled numbers refer to waveforms. • Voltages and dc between ground and measurement points.
• Through hole is omitted. Readings are taken with a digital multimeter (DC 10MΩ).

• For schematic diagrams.
• All capacitors are in µF unless otherwise noted. pF: µµF.
50 V or less are not indicated except for electrolytics and tantalums.
• Chip resistor are 1/16W unless otherwise noted.
kΩ : 1000Ω, MΩ : 1000kΩ.
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor, because
it is damaged by the heat.
• Some chip part will be indicated as follows.
