ASMT‐SxB5‐Nxxxx
Surface Mount LED Indicator
Description
Avago Power PLCC‐4 is an extension of our PLCC‐2 SMT
LEDs. The package can be driven at higher current due to
its superior package design. The product is able to
dissipate heat more efficiently compared to the
conventional PLCC‐2 SMT LEDs. In proportion to the
increase in driving current, this family of LEDs is able to
produce higher light output compared to the conventional
PLCC‐2 SMT LEDs.
These SMT LEDs have higher reliability and better
performance and are designed to work under a wide range
of environmental conditions. This higher reliability makes
them suitable for use under harsh environment and
conditions like automotive. In addition, they are also
suitable to be used in electronic signs and signals.
To facilitate easy pick and place assembly, the LEDs are
packed in EIA‐compliant tape and reel. Every reel will be
shipped in single intensity and color bin, to provide close
uniformity.
These LEDs are compatible with IR solder reflow process.
