OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/?C above 25?C.
(3) Methanol and isopropanol are recommended as cleaning agents. Housings are soluble in chlorinated hydrocarbons and
ketones. Highly activated, water soluble fluxes may attack housings in some situations.
(4) All parameters tested using pulse technique.
