This package is fully binned by
color and intensity, except for
red color. In order to facilitate
pick and place operation, these
ChipLEDs are shipped in tape
and reel, with 4000 units per
reel. These packages are compat-
ible with IR soldering process.
Description
This series of ChipLEDs is
designed with the smallest foot-
print to achieve high density of
components on board. The
HSMx-C191 has the industry
standard 1.6 mm x 0.8 mm foot-
print. Its low 0.6 mm profile and
wide viewing angle make this
LED exceptional for backlighting
applications. The available colors
in this surface mount series are
HER, orange, yellow, green, and
AS AlGaAs red.

Notes:
1. The luminous intensity I
v
is measured at the peak of the spatial radiation pattern which may not be aligned with the mechanical axis of the lamp
package.
2. The dominant wavelength
d
is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
3.
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.

Note:
1. Bin categories are established for classification of products. Products may not be available in all
categories. Please contact your Agilent representative for information on currently available bins.
