MK-R2 LEDs

PRODUCT DESCRIPTION

The XLamp

MK-R2 EasyWhite

LED

builds on the breakthrough performance

of the original MK-R by enabling

high-voltage driver solutions while

providing a small, uniform, single point

source for precise optical control. The

MK-R2 shares the same mechanical

footprint as the original MK-R, providing

customers with a seamless upgrade path

and shortening the LED luminaire and

retrot lamp design cycle.

MK-R2 LEDs are designed for high-output,

directional lighting applications and

are the ideal replacement for lighting

applications that currently use inefcient

halogen lamps. MK-R2 LEDs are optimized

for use in track, accent, lamp retrot,

downlighting and other applications

where color quality, consistency and

optical control are required.

FEATURES

• Available in 4-step and 2-step

EasyWhite bins at 2700K & 3000K,

80-CRI minimum

• Maximum drive current: 420mA

• Low thermal resistance: 1.7°C/W

• Maximum junction temperature:

150°C

• Binned at 85°C

• Viewing angle: 120°

• Unlimited oor life at

≤ 30ºC/85% RH

• Reow solderable - JEDEC

J-STD-020C

• Electrically neutral thermal path

• RoHS-compliant

• UL

recognized component

(E349212)

XLamp ® MK-R2 LED Reflow Soldering Characteristics In testing, Cree has found XLamp MK-R2 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 the solder paste used. Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment.
