This device should not be used in any type of fluid such as water, oil, organic solvent, etc When
washing is required, IPA should be used.
When the LEDs are illuminating, operating current should be decided after considering the ambient
maximum temperature.
LEDs must be stored to maintain a clean atmosphere. If the LEDs are stored for 3months or more after
being shipped from LUMIMICRO, sealed container with a nitrogen atmosphere should be used for
storage.
The LEDs must be dip soldered within seven days after opening the moisture-proof packing. Repack
unused Products with anti-moisture packing, fold to close any opening and then store in dry place.
LUMIMICRO made LEDs use a silver-plated lead frame. Siver plating can be affected by sulfur(S), or
other halogen compound. Sulfurization of lead frame may cause operational degradation. It requires
caution Repack unused Products with anti-moisture packing, fold to close any opening and then store in
dry place.
The appearance and specifications of the product may be modified for improvement without notice.
These LEDs are sensitive to the static electricity and surge. It is recommended to use a wrist band or
anti electrostatic glove when handling the LEDs. If Over voltage which exceeds the absolute maximum
rating is applied to LEDs, it will cause damage in LEDs and result in destruction. Damaged LEDs will
show some unusual characteristics such as remarkably increased leak current, turn-on voltage becomes
lower and the LEDs get unlighted at low current.
