Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) For OPB820, derate linearly 1.67 mW/° C above 25° C. For OPB821, derate linearly 1.82 mW/° C above 25° C.
(3) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and
ketones.
(4) All parameters were tested using pulse technique.
