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%,

560

47k

0.5

1

and K=10%).
