ASMT-Mx01
1W 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 motherboard.
The low profile package design is suitable for a wide
variety of applications especially where height is a con-
straint.
The package is compatible with reflow soldering. This
will give more freedom and flexibility to the light source
designer.
