OneWhite Surface-Mount PLCC-2 LED Indicator
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 and 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.
Features
High reliability package with silicone encapsulation
Compatible with reflow soldering process
High optical efficiency with 100 lm/W
Available in 8-mm carrier tape with reel diameter
180 mm
