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 × 10
47k Ω→47 × 10

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