Description
The HSMx-C177 and HSMx-C197
ChipLEDs are designed specifically
for the membrane switch applica-
tion. The request is to have the
height as low as possible while re-
taining the footprint at the optimal
size of a 0805 (2.0 x 1.25 mm) or
0603 (1.6 x 0.8 mm) device. Apart
from the membrane switch applica-
tion, the HSMx-C177 is also suit-
able for use in applications where
low height is required.
Seven different colors are avail-
able: green, red, yellow, orange,
deep red, blue, and amber. All
parts are intensity binned and
color binned (except for red
color). They come in 8 mm tape
on a 7 inch diameter reel with
4000 units per reel which makes
them compatible for automatic
placement.

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.
