4.PACKAGING
· The LEDs are packed in cardboard boxes after packaging in anti-electrostatic bags.
Please refer to “PACKING” on the following pages.
The label on the minimum 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
(1) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the epoxy bulb.
Do not use the base of the leadframe as a fulcrum during lead forming.
· Lead forming should be done before soldering.
· Do not apply any bending stress to the base of the lead. The stress to the base may damage the LED’s
characteristics or it may break the LEDs.
· When mounting the LEDs onto a printed circuit board, the holes on the circuit board should be
exactly aligned with the leads of the LEDs. If the LEDs are mounted with stress at the leads,
it causes deterioration of the epoxy resin and this will degrade the LEDs.
(2) Storage
· The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Nichia and
the storage life limits are 3 months.
If the LEDs are stored for 3 months or more, they can be
stored for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
· The lead part 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.
(3) 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.
