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
