Yellow L-1553YDT Remarks: If special sorting is required (e.g. binning based on forward voltage, Luminous intensity/ luminous flux, or wavelength), the typical accuracy of the sorting process is as follows: 1. Wavelength: +/-1nm 2. Luminous intensity/ luminous flux: +/-15% 3. Forward Voltage: +/-0.1V Note: Accuracy may depend on the sorting parameters.
