5. PCB PARTS LIST
NOTES : @ Parts marked by " NSP." are generally unavailable because they are not in our Master Spare Parts List.
@ The A\ 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%).
560 Q > 56 x 10'— S67...
47k Q — 47 x 107 > 473 ...
0.5Q—> R50... 5|[0] K
' O|K
Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors).
