4. PCB's PARTS LIST
NOTES:
Part without part number cannot be supplied.
Parts marked by "®" are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
The 4, 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%).
