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 signs in various 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 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 JEDEC MSL 3 product ESD threshold of 1000V (HBM model) per JEDEC
Applications
Home appliances Amusement machine backlighting Industrial lighting Light strips General signage backlighting Sign and display
CAUTION! LEDs are ESD sensitive. Please observe appropriate precautions during handling and processing.
