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.
Decimal points for resistor
and capacitor fixed values
are expressed as :
←
2.2 2R2
←
0.022 R022
: The power supply is shown with the marked box.
