12. PCB PARTS LIST

A

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%).

5 6 1

560 Ω → 56 × 10

1

→ 561

...................................................................

RD1/4PU J

3

→ 473

...................................................................

RD1/4PU J

4 7 3

47 kΩ → 47 × 10

.................................................................................................

R 5 0

0.5 Ω → R50RN2H K

.................................................................................................

1 R 0

1 Ω → 1R0RS1P K

5 6 2 1

5.62 kΩ → 562 × 10

.................................................................

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

B

-

Meaning of the figures and others in the parentheses in the parts list.

Example) IC 301 is on the point (face A, 91 of x-axis, and 111 of y-axis) of the corresponding PC board.
