6.3 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%,
and K=10%).
560 Ω→56 × 101→561 ........................................................ RD1/4PU 56

J
47k Ω→47 × 103→473 ........................................................ RD1/4PU 47

0.5 Ω→R50 ..................................................................................... RN2H
R 5
0K
1 Ω→1R0 ..................................................................................... RS1P 1
R 0
K
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω→ 562 × 101→5621 ...................................................... RN1/4PC
