NOTE :

Symbol indicates a resistor.

No differentiation is made between chip resistors and discrete resistors.

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and discrete capacitors.

For resistors and capacitors in the circuit diagrams, their resistance values or	B
capacitance values are expressed in codes:

			Ex. *Resistors
			Code	Practical value
			123	12k ohms
			103	10k ohms
F			*Capacitors
			Code	Practical value
			103	0.01uF
			101/10	100uF/10V
			The > mark found on some component parts indicates
		A	the importance of the safety factor of the part.
			Therefore, when replacing, be sure to use parts of
			identical designation.
