Super 0.5W White Power PLCC-4
Surface Mount LED Indicator
Data Sheet
Description
The Super 0.5W White Power PLCC-4 SMT LED is first
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 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 color bin, to provide close
uniformity.
