pieces)
To facilitate easy pick & place assembly, the LEDsare Compatible with both IR and TTW soldering process
packed in EIA‐compliant tape and reel. Every reel will be
shipped in single intensity and color bin, except red color, Applications
to provide close uniformity.
Electronic signs and signals
- Interior full color sign
These LEDs are compatible with IR solder reflow process.
- Variable message sign
Due to the high reliability feature of these products, they Office automation, home appliances, industrial
can also be mounted using through‐the‐wave soldering
equipment
process.
- Front panel backlighting
- Push button backlighting
The super wide viewing angle at 120˚ makes these LEDs
- Display backlighting
ideally suited for office equipment, industrial equipment,
and home appliances. The flat top emitting surface makes
it easy for these LEDsto mate with light pipes. With the
built‐in reflector pushing up the intensity of the light
output, these LEDs are also suitable to be used as LED
pixels in interior electronic signs.
CAUTION: ASMT‐UxB4‐Pxxx LEDs are Class 2 ESD sensitive. Please observe appropriate precautions during handling and
processing. Refer to Avago Application Note AN‐1142 for additional details.

Handling Precaution
The encapsulation material of the product is made of
silicone for better reliability of the product. As silicone is a
soft material, please do not press on the silicone or poke a
sharp object onto the silicone. These might damage the
product and cause premature failure. During assembly or
handling, the unit should be held on the body only. Please
refer to Avago Application Note AN 5288 for detail
information.
Moisture Sensitivity
This product is qualified as Moisture Sensitive Level 2a per
Jedec J‐STD‐020. Precautions when handling this moisture
sensitive product is important to ensure the reliability of
the product. Do refer to Avago Application Note AN5305
Handling of Moisture Sensitive Surface Mount Devices for
details.
A. Storage before use
Unopen moisture barrier bag (MBB) can be stored at
