Note :
•
All capacitors are in µF unless otherwise noted.
•
pF : µµF 50WV or less are not indicated except for
electrolytic types.
•
Indication of resistance, which does not have one for
rating electrical power, is as follows.
Pitch : 5mm
Electrical power rating : 1/4W
•
Chip resistors are 1/10W
•
All resistors are in ohms.
k = 1000 ohms, M = 1000,000 ohms
•
•
•
•
•
All variable and adjustable resistors have
characteristic curve B, unless otherwise noted.
•
All voltages are in Volts.
•
Readings are taken with a 10Mohm digital mutimeter.
•
Readings are taken with a color bar input signal.
•
Voltage variations may be noted due to normal production
tolerences.
