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.
