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. The > mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation.
For resistors and capacitors in the circuit diagrams, their resistance values or capacitance 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

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. The > mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. For resistors and capacitors in the circuit diagrams, their resistance values or capacitance 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
