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

Ex. *Resistors Code Practical value 123 12k ohms 103 10k ohms

*Capacitors Code Practical value 103 0.01uF 101/10 100uF/10V

The > mark found on some component parts indicatesthe importance of the safety factor of the part.Therefore, when replacing, be sure to use parts ofidentical designation.

Symbol indicates a resistor.No differentiation is made between chip resistors anddiscrete resistors.

NOTE :

Symbol indicates a capacitor.No differentiation is made between chip capacitors anddiscrete capacitors.
