ASMT-Ax00
1W Power LED Light Source
Data Sheet
Description
The ASMT-Ax00 series of 1W Power LEDs are high performance
energy efficient devices which can handle high driving current
and high temperatures. The exposed pad design enables
excellent heat transfer from the package to the motherboard.
An electrically isolated metal slug option is also available.
The White Power LED is available with color temperatures
ranging from 2700K to 10000K.
The low profile package design is suitable for a wide variety of
applications especially where height is a constraint and the
package foot print is compatible with most high power LEDs
available in the market today.
This package is compatible with reflow soldering process.
Features
Available in red, amber, blue, royal blue, cyan, green, cool
white, neutral white, and warm white colors
