The small size, low 1.1 mm
profile and wide viewing angle
make these LEDs excellent for
backlighting applications and
front panel illumination. They
are compatible with IR reflow
soldering processes.

Description
These single and bicolor LEDs
are designed in an industry
standard package for ease of
handling and use. Five different
LED colors are available in two
compact, low profile, single color
packages. The 3.2 x 1.6 mm is
an excellent all around package,
and the small 2.0 x 1.25 mm
package is designed for applica-
tions where space is limited.
The single color LEDs have

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.
4. Chip LEDs are supplied in 8 mm embossed tape on 178 mm (7 in.) diameter reels, with 3000 devices per reel. Minimum order
quantity and order incremenets are in quantity of reels only.
