Available in white (2600 K to 8300 K CCT) with CRI options of 80, 85, and 90, and in royal blue.
White LEDs can be configured in parallel or series.
ANSI-compatible sub-bins.
Maximum drive currents: 350 mA (parallel), 175 mA (series), 250 mA (royal blue).
120° viewing angle with uniform chromaticity.
Electrically neutral thermal path and RoHS-compliant.

Specifications

Thermal resistance: 13 °C/W.
Viewing angle: 120° for white, 125° for royal blue.
Temperature coefficient of voltage: -3.4 mV/°C (parallel), -6.8 mV/°C (series).
ESD classification: Class 2 (parallel), 8000 V (series).
Forward voltage: 3.2-3.4 V (parallel), 6.4-7.0 V (series).
LED junction temperature: 150 °C.

Flux Characteristics
Includes base order codes for various color temperatures and CRI levels, with a tolerance of ±7% on flux and power measurements.

Thermal Design
Focuses on minimizing thermal resistance to optimize lamp life and optical characteristics, with graphs showing maximum current versus ambient temperature.

Reflow Soldering Characteristics
Compatible with JEDEC J-STD-020C standards, with guidelines for lead-based and lead-free soldering, recommending the lowest possible reflow temperature.

Notes
Includes lumen maintenance projections using IES LM-80-08 and TM-21-11 methods, and moisture sensitivity precautions.

Handling and Storage Recommendations
XLamp ML-C LEDs should remain in sealed moisture-barrier packaging until use. If exposed to humidity, they must be baked before soldering.

Baking Conditions
LEDs exposed to humidity should be baked at 70°C for 24 hours to reset exposure time.

Storage Conditions
Store LEDs in a rigid metal container with desiccant or a dry, nitrogen-purged cabinet, maintaining <30°C and <60% RH.

RoHS Compliance
Complies with RoHS2 Directive 2011/65/EU, with restricted materials below maximum concentration values.

Vision Advisory
Avoid looking at exposed LED lamps in operation to prevent eye injury. Refer to Cree's LED Eye Safety Application Note.

Mechanical Dimensions and Packaging
Includes mechanical dimensions with tolerances and packaging details, conforming to EIA-481D standards.
