Notes:
(1) Derate linearly 1.67 mW/° C above 25° C for L Series.
(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. Plastic housing is soluble in chlorinated hydrocarbons and
ketones.
(4) The W Series includes wire terminations of 24” (610 mm) 7-strand, 26 AWG UL insulated wire on each terminal. Each device
incorporates a wire strain relief at the housing surface. The insulation functions and colors are: anode (red), cathode (black),
phototransistor collector (white) and phototransistor emitter (green).
(5) All parameters tested using pulse technique.
