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%).
