NOTES:
(1) RMA flux is recommended. Duration can be ex tended to 10 seconds maximum when flow
soldering. Max imum 20 grams force may be applied to the leads when soldering.

(3) E
e(APT)
is a measurement of the average apertured radiant en ergy incident upon a sensing
area 0.081” (2.06 mm) in diameter, perpendicular to and centered on the mechanical axis of
the “
emitting surface”and 0.400” (10.16 mm) from the measurement surface. E
e(APT)
is not
necessarily uniform within the measured area.
Description
The OP268FPS contains an 850 nm
gallium aluminum arsenide infrared
emitting diode molded in an
“
end-looking” miniature black package.
This device has a wide radiation angle
due to its flat emitting surface. The point
source GaAIAs IRED emits photons from
a 0.004” diameter area centered with the
optical centerline. Small size and 0.100”
(2.54 mm) lead spacing allow
considerable design flexibility.
The stable V

vs. Temperature
characteristic make them ideal for
applications where voltage is limited
(such as battery operation).
The low t

f
make them ideal for high
speed operation.
