ASMT-Mx00
1 W Power LED Light Source
Data Sheet
Description
1W Power LED Light Source is a high performance
energy efficient device which can handle high thermal
and high driving current. The exposed pad design has
excellent heat transfer from the package to the mother-
board.
The Warm White Power LED is available in various color
temperature ranging from 2600K to 4000K. The product
has high Color Rendering Index (CRI) which provides
excellent color perception and visual clarity.
The low profile package design is suitable for a wide
variety of applications especially where height is a
constraint.
The package is compatible with reflow soldering
process. This will give more freedom and flexibility to
the light source designer.
