I checked the data sheet of Samsung SPMWH22286D5WNRUS3 .
Data sheet does not specify the NRU option .
What does it mean NRU
Hello @cpassarelli
WN suffix calls out forward voltage with specific bin codes to specify this value. W indicates the forward voltage and N is referenced for the package size of 4000pcs.
RU suffix calls out color temperature (CCT) 5000K with bin codes as well to specify the chromaticity Bins.
The R specifies this CCT and the U dictates that this is for the entire reel binned at MacAdam 3-step binning. containing only a single bin.
