5. PCB PARTS LIST
NOTES:
¶
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
¶
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.
¶
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
