CAUTIONS
(1) Storage
(2) Directions for Use
(3) Handling Precautions
● Absorbed moisture in LED packages can vaporize and expand during soldering, which can cause interface delamination
● Although the leads or electrode pads (anode and cathode) of the product are plated with gold,
● Do not use sulfur-containing materials in commercial products. Some materials, such as seals and adhesives, may contain sulfur.
● To prevent water condensation, please avoid large temperature and humidity fluctuations for the storage conditions.
● When designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating.
● LEDs should be operated in forward bias. Driving circuits must not subject LEDs to either forward or reverse voltage while off.
● For stabilizing the LED characteristics, it is recommended to operate at greater than 10% nominal current.
● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.
● This LED also emits visible light. Please take notice of visible light spectrum,
● Do not handle LEDs with bare hands, it may contaminate the LED surface and affect optical characteristics.
● When handling the product with tweezers, be careful not to apply excessive force to the resin.
● Dropping the product may cause damage.
● Do not stack assembled PCBs together. Failure to comply can cause the resin portion of the product to be cut, chipped,
Storage
and result in optical performance degradation. Products are packed in moisture-proof aluminum bags
to minimize moisture absorption during transportation and storage.
Included silica gel desiccants change from blue to red if moisture had penetrated bags.
prolonged exposure to a corrosive environment might cause the gold plated the leads or electrode pads to tarnish,
and thus leading to difficulties in soldering. If unused LEDs remain, they must be stored in a hermetically sealed container.
Nichia recommends using the original moisture-proof bag for storage.
The contaminated plating of LEDs might cause an open circuit. Silicone rubber is recommended as a material for seals.
Bear in mind, the use of silicones may lead to silicone contamination of electrical contacts inside the products,
caused by low molecular weight volatile siloxane.
Operating at a constant current per LED is recommended. In case of operating at a constant voltage, Circuit B is recommended.
If the LEDs are operated with constant voltage using Circuit A, the current through the LEDs may vary due to the variation
in Forward Voltage characteristics of the LEDs.
Continuous reverse voltage can cause migration and LED damage.
in case you use this LED as light source of sensors etc.
In the worst case, catastrophic failure from excess pressure through wire-bond breaks and package damage may result.
Otherwise, The resin can be cut, chipped, delaminate or deformed, causing wire-bond breaks and catastrophic failures.
