DESCRIPTION
Exceptional light output
typifies these devices and
provides for their use over a
broad range of drive currents.
The LED material is based on double
heterojunction (DH) AIGaAs/GaAs
technology.
NOTES:
1. ALL DIMENSIONS ARE IN INCHES (mm).
2. TOLERANCE ARE ±.010” UNLESS OTHERWISE SPECIFIED.
3. AN EPOXY MENISCUS MAY EXTEND ABOUT .040”(1 mm)
DOWN THE LEADS.
