Description
The Envisium
TM
0.5W Power PLCC-4 SMT LED is an
extension of Envisium
TM
Power PLCC-4 SMT LEDs. 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 Envisium
TM
Power PLCC-
4 SMT LEDs. These LEDs produce higher light output with
better flux performance compared to the Envisium
TM
Power PLCC-4 SMT LED.
The Envisium
TM
0.5W 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 (except for red),
to provide close uniformity. These LEDs are compatible
with the IR solder reflow process.
Envisium
TM
0.5W Power PLCC-4 SMT LED is available in
red orange & amber colors.
