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
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.
Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.
NOTE :
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and
discrete capacitors.
