Notes:
1. The optical power is determined by measuring die mounted on TO-46 headers inside an integrating sphere. An index matching encapsulent is not used to enhance this measurement.
2. The dominate wavelength is calculated from the 1931 20 CIE Chromaticity Diagram.
3. A tolerance of ± 15% on brightness level, and ± 2 nm on chromaticity, due to measuring variations applies.
4. Maximum ratings are package dependent. The above ratings were determined using a T-1 ¾ Pkg for characterization . Ratings for other packages may differ. The forward currents are not limited by the die but by the effect of the package on the junction temperature of the LED.
5. All die products conform to the listed specifications when packaged and operated within the maximum limits shown above. Typical values are provided for information only but are within the range of average values of acceptable sample sizes.
