Description
The HSMx-C260 is a reverse
mountable chip-type LED for
lighting the non-component side
of a PC board. In this reverse
mounting configuration, this
LED is designed to emit light
through a small cut-out hole in
the PC board.
The HSMx-C260 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
applications.

Notes:
1. The luminous intensity, Iv, is measured at the peak of the spatial radiation pattern, which may not be aligned with the mechanical
axis of the lamp package.
2.
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
