Super 0.5W Power PLCC-4
Surface Mount LED Indicator
Data Sheet
Description
The Super 0.5W Power PLCC-4 SMT LED is Blue 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 Power PLCC-4 SMT LEDs are designed for
higher reliability, better performance, and operate under
a wide range of environmental conditions. The perfor-
mance characteristics of these new mid-power LEDs make
them uniquely suitable for use in harsh conditions 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.
