¡Operating and handling precautions

(1) This product employs open type package. Be careful not to touch gold wires, laser chips, or monitor sub-mount chips directly, or

characteristics may be damaged.

(2) The lead pins of this product consist of silver-plating.

Do not operate under the conditions of freezing or dew formation. The use in such conditions may cause short circuits due to silver

migration.

(3) Please finish soldering within 7 days, or keep the products in the N2-purged box after opening the package to prevent silver oxidization or

damage to solderability.
