Lu CHECKED: Allen Liu DRAWN: S.H.CHEN ERP:1101002185 Super Bright Red WP1553SRDT Remarks: If special sorting is required (e.g. binning based on forward voltage, luminous intensity, or wavelength), the typical accuracy of the sorting process is as follows: 1. Wavelength: +/-1nm 2. Luminous Intensity: +/-15% 3. Forward Voltage: +/-0.1V Note: Accuracy may depend on the sorting parameters.
