ASMT-MxA0
1W Power LED Light Source on MCPCB
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 Cool White Power LED is available in various color
temperature ranging from 4000K to 10000K and Warm
White Power LED 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 con-
straint.
