ASDL-4264
High Eciency T-1 ¾ (5mm) Infrared (940nm) Lamp
Data Sheet
Description
ASDL-4264 is a Infrared emitter that is optimized for high
eciency at emission wavelength of 940nm. This device
is designed for high current and low forward voltage ap-
plications. It is encapsulated in T1-3/4 (5mm) package
and is suitable for high performance replacements of
standard emitters.
