GaAlAs Infrared Emitting Diodes
Flat T-1¾ (5 mm) P la stic Packag e — 880 nm
PACKA GE DIMENSIONS inch (mm)
VTE1281F
DESCRIPTION
CHIP SIZE: .015" x .015"
This 5 mm diameter plastic packaged emitter has no lens. It is designed to be coupled to plastic fibers or used to illuminate an external
lens. It contains a medium area, single wirebonded, GaAlAs 880 nm chip and is designed to be cost effective in moderate pulse drive
applications.
