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.
