+ Unless otherwise specified, any resistance is expressed
in ohms. K = 1000 ohms and M = 1000K ohms. The
rated power is 1/4W.
-The symbol ‘A/\/\’ means ordinary resistor and the
symbol “AMS means printed resistor.
4. Capacitor:
- Unless otherwise specified, any capacitance is expressed
in microfarad. P = picofarad
-The types of capacitors are seen from the symbols ML
(mylar capacitor), S (polystyrene film capacitor) CH,
UJ (temperature compensating ceramic capacitor) and
PP (polypropylene capacitor).
5. Electrolytic capacitor:
The expression “capacitance/withstand voltage” is used.
6. Voltage measurement in each part is made with no signal
input and with the following conditions.
