[1] 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 "Fus-
ible" 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
