•All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytic and tantalums.
•All electrolytics are 50V unless otherwise specified.
•Indication of resistance, which does not have one for rating electrical power, is as follows:
Pitch: 5mm
Rating electrical power 1/4W (CHIP: 1/10W)
•All resistors are in ohms.
K = 1000 M = 1000K
•All variable and adjustable resistors have characteristic
