Notes on schematic diagram

Resistor:
•
To differentiate the units of resistors, such symbol
as K and M are used: the symbol K means 1000
ohm and the symbol M means 1000 kohm and the
resistor without any symbol is ohm-type resistor.
Besides, the one with "Fusible" is a fuse type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used:
this symbol P means pico-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression "capacitance/
withstand voltage" is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
