GaAlAs HIGH POWER T-1 3/4 PACKAGE
Description Package Dimensions
The MIE-544H4 is a GaAlAs infrared LED having a
peak wavelength at 850nm. It features ultra-high power,
φ5.05
(.200)
high response speed and molded package with higher
radiant intensity. In addition to improving the S/N ratio
in applied optical systems, the MIE-544H4 has greatly
