PCB PARTS LIST
NOTES:
e Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
e 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.
e Parts marked by "@"
are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
© 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%).
