ASMT-MYA0
1W Power LED Light Source on MCPCB
Data Sheet
Description
Avago Technologies’ 1W Warm White Power LED 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 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.
