High Efficiency Red / Yellow L-937EYW 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. SPEC NO: DSAB7199 REV NO: V.6 DATE: MAR/23/2005 APPROVED: J.
