0.022 R022

←

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.

←

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.
