ASMT-UWB1-NX302
OneWhite Surface Mount PLCC-2 LED Indicator
Data Sheet
Description
This family of SMT LEDs is packaged in the industry
standard PLCC-2 package. These SMT LEDs have high
reliability performance and are designed to work under
a wide range of environmental conditions. This high
reliability feature makes them ideally suited to be used as
interior signs application conditions.
To facilitate easy pick & place assembly, the LEDs are
packed in EIA-compliant tape and reel. Every reel will be
shipped in single intensity and color bin.
These LEDs are compatible with reflow soldering process.
The wide viewing angle at 120° makes these LEDs ideally
suited for panel, push button, office equipment, industrial
equipment, and home appliances. The flat top emitting
surface makes it easy for these LEDs to 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.
