0.25W Cool White Power PLCC4
Surface Mount LED
Datasheet
Description
The Avago Technologies ASMT-UWBx series 0.25W Cool
White Power PLCC4 SMT LED lamps use InGaN chip
technology and superior package design to enable them to
produce higher light output with better flux performance. They
can be driven at high current and are able to dissipate the heat
more efficiently resulting in better performance with higher
reliability. These lamps are able operate under a wide range of
environmental conditions making them ideal for various
application including fluorescent replacement, under cabinet
lighting, retail display lighting and panel lights.
To facilitate easy pick and place assembly, the LEDs are
packed in EIA-compliant tape and reel. Every reel is shipped in
single intensity and color bin, to provide close uniformity.
CAUTION:
Static sensitive device. Please observe appropriate
precautions during handling and processing.
