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.
F
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
