Super 0.5W Cool White Power PLCC-4
Surface Mount LED Indicator
Data Sheet
Description
The Super 0.5W Cool White Power PLCC-4 SMT LED is first
Cool white mid-Power PLCC-4 SMT LEDs using InGaN
chip technology. The package can be driven at high
current due to its superior package design. The product
is able to dissipate the heat more efficiently compared to
the Power PLCC-4 SMT LEDs. These LEDs produce higher
light output with better flux performance compared to
the Power PLCC-4 SMT LED.
The Super 0.5W Cool White Power PLCC-4 SMT LEDs are
designed for higher reliability, better performance, and
operate under a wide range of environmental conditions.
The performance characteristics of these new mid-power
LEDs make them uniquely suitable for use in harsh condi-
tions such as in automotive applications, and in electron-
ics signs and signals.
To facilitate easy pick and place assembly, the LEDs are
packed in EIA-compliant tape and reel. Every reel is
shipped in single intensity and sub color bin, to provide
close uniformity.
