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 micro-micro-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

(PP): Polypropylene type
