Description
The HSMx-L640 is a Chip LED
with an integrated lens. The lens
concentrates the emitted light
into a narrow viewing angle,
which has the effect of doubling
the on-axis intensity. These
LEDs are optimum for light
piping, backlighting buttons and
switches and applications, where
as much flux as possible is
required on axis.
The available colors are 571 nm
Green, 586 nm Yellow, 604 nm
Orange, 626 nm Red, and
639 nm Deep Red.
The 3.0 x 1.5 mm package
closely matches industry standard
sizes for chip capacitors which
makes it compatible with
automated pick and place
equipment.
This package is compatible with
IR and convective reflow
soldering processes.

Notes:
3. Derate linearly as shown in Figure 4.
4. Drive currents between 1 mA and 25 mA are recommended for best long term performance.
5. Operating at currents below 1 mA is not recommended. Please contact your Agilent representative
for further information.
6. Maximum temperature for tape and reel packaging is 60
