ML-B LEDs

PRODUCT DESCRIPTION

The Cree XLamp

ML-B LED

brings lighting-class reliability and

performance to 1/4-watt LEDs.

The XLamp ML-B LED expands

Cree’s lighting-class leadership

to linear and distributed lighting

applications. With XLamp LED

lighting-class reliability, a wide

viewing angle, uniform light

output, and industry-leading

chromaticity binning in a 3.5-mm

X 3.5-mm package, the XLamp

ML-B LED continues Cree’s history

of segment-focused product

innovation in LEDs for lighting

applications.

The XLamp ML-B LED brings

high performance and a smooth

look to a wide range of lighting

applications, including linear

lighting, uorescent retrots and

retail-display lighting.

FEATURES

• Available in white (2200 K and

2600 K to 8300 K CCT) and

80-, 85- and 90-CRI minimum

• ANSI-compatible sub-bins

• Maximum drive current:

175 mA

• 120° viewing angle, uniform

chromaticity profile

• Electrically neutral thermal

path

• RoHS and REACh-compliant

• UL-recognized component

(E349212)

XLamp ® ML-B LEDs Reflow Soldering Characteristics In testing, Cree has found XLamp ML-B LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed below. As a general guideline, Cree recommends that users follow the recommended soldering profile provided by the manufacturer of solder paste used. Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment. Profile Feature Lead-Based Solder Lead-Free Solder 3 °C/second max.

XLamp ® ML-B LEDs Notes Measurements The luminous flux, radiant power, chromaticity and CRI measurements in this document are binning specifications only and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number of factors that are not within Cree’s control and are not intended or provided as operational specifications for the products.

XLamp ® ML-B LEDs Storage Conditions XLamp ML-B LEDs that have been removed from the original MBP but not soldered should be stored in one of the following ways: • Store the parts in a rigid metal container with a tight-fitting lid. Verify that the storage temperature is <30 °C, and place fresh desiccant and an RH indicator in the container to verify that the RH is no greater than 60%.
