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%).
560 Ω → 56 × 10
1
→ 561
...................................................................
RD1/4PU J
47 kΩ → 47 × 10
3
→ 473
...................................................................
RD1/4PU J
0.5 Ω → R50
.................................................................................................
RN2H K
1 Ω → 1R0
.................................................................................................
RS1P K
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62 kΩ → 562 × 10
1
→ 5621
