Maximum ratings are package-dependent. The above ratings were determined using a 3.45 x 3.45 mm SMT without an encapsulant
for characterization. Ratings for other packages may differ. The junction temperature should be characterized in a specific package
to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds). See Cree EZBright Applications
Note for assembly-process information.
All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 350 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given
are within the range of average values expected by the manufacturer in large quantities and are provided for information only. All
measurements were made using a Au-plated TO39 header without an encapsulant. Optical characteristics were measured in an
integrating sphere using Illuminance E.
