Notes:
(1) All parameters tested using pulse technique.
(2) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(3) Methanol or isopropanol are recommended as cleaning agents. The plastic housing is soluble in chlorinated hydrocarbons and
keytones.
(4) Derate linearly 1.33 mW/° C above 25° C.
(5) Ee(APT) is a measurement of the average apertured radiant energy incident upon a sensing area 0.250” (6.350 mm) in diameter,
which is perpendicular to and centered to the mechanical axis of the emitting surface at a distance of 0.466” (11.837 mm).
Ee(APT) is not necessarily uniform within the measured area.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
