DESCRIPTION
VSMF4720 is an infrared, 870 nm emitting diode in GaAlAs
double hetero (DH) technology with high radiant power and
high speed, molded in a PLCC-2 package for surface
mounting (SMD). A 19" chip provides outstanding low
forward voltage and radiant intensity even at 1 A pulse
current.
APPLICATIONS
• High speed IR data transmission
• High power emitter for low space applications
• High performance transmissive or reflective sensors

MISSING DEVICES
A maximum of 0.5 % of the total number of components per
reel may be missing, exclusively missing components at the
beginning and at the end of the reel. A maximum of three
consecutive components may be missing, provided this gap
is followed by six consecutive components.

COVER TAPE REMOVAL FORCE
The removal force lies between 0.1 N and 1.0 N at a removal
speed of 5 mm/s. In order to prevent components from
popping out of the blisters, the cover tape must be pulled off
at an angle of 180° with regard to the feed direction.

The tape leader may include the carrier tape as long as the
cover tape is not connected to the carrier tape. The least
component is followed by a carrier tape trailer with a least
75 empty compartements and sealed with cover tape.
