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) Distance = 1” (from front of package to a 90% diffuse reflective white card)
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
