Duration can be ex tended to 10 seconds maximum when flow soldering. A maximum of 20 grams force may be applied to the leads when soldering. (2) Derate linearly 1.33 mW/ above 25 C . (3) E e(APT) is a measurement of the average apertured radiant in cidence upon a sensing area 0.180"(4.57 mm) in diameter, perpendicular to and centered on the mechanical axis of the lens, and 0.653"(16.6 mm) from the measurement surface. Ee(APT) is not necessarily uniform within the measured area. Description The OP245PS is an 850 nm, infrared emItting diode molded in IR transmissive amber-tinted epoxy packages. The side-looking package is for use in PC board mounted slotted switches or as easily mounted interrupt detectors. 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 operations.
