Cree XTE Series on Board
Cree XTE Series
Designed to accelerate LED lighting adoption, the XTE LED delivers up to 148 lumens and 148 lumens
per watt in cool white (6000K) or up to 114 lumens and 114 lumens per watt in warm white (3000K),
0
both at 350 mA and 85 C.

ESD Classification (HBM per MIL-STD-883D) -- Class 2 --
* Exceeding maximum ratings may damage the LED and cause potential safety hazards.
* Elevated operating temperatures can be expected to negatively impact the service life (lumen output)
* All data is related to entire assembly. Data reflects statistical mean values. Actual data may differ depending on variances in the
manufacturing process.
* End users need to take into account the lumen depreciation as the temperature rises with various thermal solutions installed.
* It is highly recommended for the user to review the CREE XTE Series page for additional and most recent technical data at

Note 1: Using continuously under elevated loads (i.e. the application of high temperature/current/voltage or a significant change in
temperature, etc.) may cause this product to significantly decrease in reliability even if the operating conditions are within the
absolute maximum ratings.
0
Note 2: The thermal resistance from the LED junction to ambient temperature, Rth(j-a), should be kept below 10 C/W so that the LED
is not exposed to a condition beyond the absolute maximum ratings.
Note 3: The temperature of the LED assembly must be measured at the T -point according to EN60598-1 in a thermally constant
C
status with a temperature sensor or a temperature sensitive label.
