GaAlAs T-1 PACKAGE
INFRARED EMITTING DIODE
MIE-304H4
Description
Package Dimensions
The MIE-304H4 is a GaAlAs infrared LED having a
peak wavelength at 850nm molded in water clear
plastic package. The forward voltage at low current
and at high pulse current roughly correspond to the
low values of the standard technology.
