Agilent HSMx-C265
Surface Mount Chip LEDs
Data Sheet
Description
The HSMx-C265 is a reverse mount-
able chip-type LED for lighting the
non-component side of a PCB
board. In this reverse mounting
configuration, this LED is designed
to emit light through a small cut-out
hole in the PC board.
Features
· Reverse mountable
· Undiffused optics
· Small 3.4 x 1.25 mm footprint
· Operating temperature range of
30
°
C to +85
°
C
· Compatible with IR solder reflow
· Four colors available: red, orange,
yellow, and green
· Available in 8 mm tape on
7" (178 mm) diameter reels
Applications
· Keypad backlighting
· Symbol backlighting
· LCD backlighting
· Status indication
· Front panel indicator

The HSMx-C265 is available in
four colors. The small size, narrow
footprint, and low profile make
this series of LEDs excellent for
backlighting, status indication,
and front panel illumination
application.

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 Chromatically 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.
