Notes:

1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum 20 grams force

may be applied to the leads when soldering.

2. Derate linearly 1.33 mW/° C above 25° C.

3. Isolation voltage testing is required.

4. Storage and Operating temperature values are based on the plastic optical interface temperature ratings. Please reference UL1577

and UL file AVLVZ.E89328
