5. PCB PARTS LIST
NOTES :� Parts marked by O 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. 1When 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%).
1
560 W = 56 ´ 10= 561...................................................RD1/4PU 5 6 1 J
3
47k W = 47 ´ 10 = 473..................................................RD1/4PU 4 7 3 J
0.5 W = R50......................................................................RN2H a 5 0 K
1 W = 1R0.........................................................................RS1P 1 a 0 K
Ex. 2When there are 3 effective digits (such as in high precision metal film resistors).
1
5.62k W = 562 ´ 10 = 5621...........................................RN1/4PC 5 6 2 1 F
