Character representation

The resistance value identification of the product is generally a 4-character code. The following two common expressions are given below.
（1）Use “R” for decimal point of “Ω”, and the number following “R” is a valid number.
Example: The product code of 5mΩ is R005
The product code of 50mΩ is R050
The product code of 100mΩ is R100
（2）Use “m” for decimal point of “mΩ”, and the number following “m” is a valid number.

Example: 0.5mΩ product code is 0m50
The product code of 1.5mΩ is 1m50
The product code of 15.5mΩ is 15m5
