· The LEDs are packed in cardboard boxes after packaging in stick.
Please refer to “STICK DIMENSIONS” and “PACKING” on the following pages.
The label on the packing unit shows ; Part Number, Lot Number, Ranking, Quantity
· In order to protect the LEDs from mechanical shock, we pack them in cardboard boxes for transportation.
· The LEDs may be damaged if the boxes are dropped or receive a strong impact against them,
so precautions must be taken to prevent any damage.
· The boxes are not water resistant and therefore must be kept away from water and moisture.
· When the LEDs are transported, we recommend that you use the same packing method as Nichia.

7.CAUTIONS
The LEDs are devices which are materialized by combining Blue LEDs and special phosphors.
Consequently, the color of the LEDs is changed a little by an operating current.
Care should be taken after due consideration when using LEDs.
(1) Storage
· Storage Conditions
Before opening the package :
The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a
year.
When storing the LEDs, moisture proof packaging with absorbent material (silica gel)
is recommended.
After opening the package :
The LEDs should be kept at 30°C or less and 70%RH or less.
The LEDs should be soldered
within 168 hours (7days) after opening the package.
If unused LEDs remain, they should be
stored in moisture proof packages, such as sealed containers with packages of moisture absorbent
material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag
and to reseal the moisture proof bag again.
· If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
time, baking treatment should be performed using the following conditions.
Baking treatment : more than 24 hours at 85°C
· Nichia LED leadframes are silver plated copper alloy. The silver surface may be affected by
environments which contain corrosive substances. Please avoid conditions which may cause the LED
to corrode, tarnish or discolor. This corrosion or discoloration may cause difficulty during soldering
operations. It is recommended that the LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
(2) Recommended circuit
· In designing a circuit, the current through each LED must not exceed the absolute maximum rating
specified for each LED. 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 (V
F
) of the LEDs. In the
worst case, some LED may be subjected to stresses in excess of the absolute maximum rating.
(A)
...
(B)
...
· This product should be operated in forward bias. A driving circuit must be designed 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.
