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.
