CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

[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 resis-

tor 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
