¡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.
Notice
In the absence of confirmation by device specification sheets, SHARP takes no responsibility for any defects that may occur in equipment using any SHARP
devices shown in catalogs, data books, etc. Contact SHARP in order to obtain the latest device specification sheets before using any SHARP device.
