12. 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 47 k ohm (tolerance is shown by J = 5%,
and K = 10%).
560 Ω
47 kΩ
0.5 Ω
1 Ω
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62 kΩ →
