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
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 electronics
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 color bin, to provide close
uniformity.
