CAUTIONS
(1) Storage
(2) Directions for Use
● This product is compliant to JEDEC MSL 3 or equivalent. See IPC/JEDEC STD-020 for the details of the moisture sensitivity levels.
● Interface delamination can occur due to vaporization and expansion of absorbed moisture
● After opening the moisture-proof aluminum bag, the products should be completed soldering process
● After the "Period After Opening" specified above, or if the desiccants (silica gel) are no longer blue, the products need to be baked.
● 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 avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly.
● In designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating specified for each LED.
● This product should be operated in forward bias. A driving circuit must be designed
● For stabilizing the LED characteristics, it is recommended to operate at 10% of the rated current or higher.
● Care must be taken to ensure that the reverse voltage will not exceed the Absolute Maximum Rating
● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.
Storage
Baking
in the LED packages caused by soldering heat, which may result in degradation in optical performance.
To minimize moisture absorption into the products during the transportation and storage, the products are packed
in a moisture-proof aluminum bag. Desiccants (silica gel) inside the packing turn from blue to red as it absorbs moisture.
within the range of the conditions above. If unused LEDs remain, they should be stored with desiccants (silica gel)
in hermetically sealed container. Nichia recommends using the original moisture-proof bag for storage.
Note that baking must only be done once.
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.
It is recommended to use Circuit B which regulates the current flowing through each LED. In the meanwhile,
when driving LEDs with a constant voltage in Circuit A, the current through the LEDs may vary due to the variation
in Forward Voltage characteristics of the LEDs.
so that the product is not subjected to either forward or reverse voltage while it is off. In particular,
if a reverse voltage is continuously applied to the product, such operation can cause migration resulting in LED damage.
