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. (2) Derate linearly 1.33 mW/C above 25C. (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. Ee(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 VF vs. Temperature characteristic make them ideal for applications where voltage is limited (such as battery operation). The low tr /tf make them ideal for high speed operation.
