Data Sheet
Description
The Long-Life White PLCC-4 SMT LEDs is the latest
extension to our White PLCC-4 packages where besides
having higher flux output, the Long-Life White PLCC-4
is designed to work under a wide range of environment
condition, with reliable and stable performance. The
structure and materials used for Long-Life White PLCC-4
enable the packages to endure minimal degradation and
hence consistent performance throughout the product
life time. Moreover, the Long-Life White PLCC-4 SMT LEDs
is a 8-binned product for color, an enhance feature from
the previous PLCC-4 white who is binned with 6 color
binning only. These tigher color binning will ensure better
color grouping with better uniformity.
The Long-Life White PLCC-4 SMT LEDs is suitable to be
used in Interior Automotive application, Electronics Signs
and Signals application. Besides that, the super wide
viewing angle at 120° makes these LEDs ideally suited for
instrument cluster panel, push button, or general back-
lighting in automotive interior, office equipment, industri-
al equipment, and home appliances. The flat top emitting
surface makes it easy for these LEDs to mate with light
pipes. With the built-in reflector pushing up the intensity
of the light output, these super high brightness LEDs can
be used in localized area ambience lighting in applica-
tions such as vanity mirror light, cabin light, and car door
puddle light. The white color backlighting is suitable to
backlight color LCD screens in applications such as GPS
(global positioning system) screen in cars.
To facilitate easy pick and place assembly, the LEDs are
packed in EIA-compliant tape and reel. Every reel will be
shipped in single intensity and color bin, to provide close
uniformity.
These LEDs are compatible with IR solder reflow process.
