Symbol indicates a resistor.

: The power supply is shown with the marked box.

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
