PRODUCT FAMILY DATA SHEET
Cree® PLCC4 SMD LED
CLA2A-WKW
PRODUCT DESCRIPTION
SMD LEDs is packaged in the industry
standard package. These LEDs have
high reliability performance and are
designed to work under a wide range
of environmental conditions.
This high reliability feature makes
them ideally suited to be used under
illumination application conditions.
Its wide viewing angle makes these
LEDs ideally suited for channel letter,
or general backlighting and illumina-
tion applications. The flat top emitting
surface makes it easy for these LEDs
to mate with light pipes.
FEATURES
• Size (mm):3.2 x 2.8
• Color Temperatures(K):
Cool White :
Min . (4600) / Typical (5500)
• Luminous Intensity (mcd)
CLA2A-WKW:
(2240 - 5600)
• Viewing angle: 120 degree
• Lead-Free
• RoHS Compliant
APPLICATIONS
• Light Strip
• Channel Letter
