14. CAUTIONS:
(1)Storage
‧ Before opening the package :
The LEDs should be kept at 30℃ or less and 30%RH~85%RH. The LEDs should be
used within a year. When storing the LEDs, moisture proof packaging with desiccant
(Silica gel) is recommended.
‧ After opening the package :
The LEDs should be kept at 30℃ or less and 30%RH~70%RH.The LEDs should be
soldered within 168hours (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 desiccant (Silica ge1), or reseal the moisture proof bag again.
If the moisture desiccant (Silica ge1)has faded away or the LEDs have exceeded the
storage time, baking treatment should be performed using the fo1lowing conditions.
Baking treatment: more than 24 hours at 65℃.
Please avoid conditions which may cause the LED to corrode, tarnish or disco1or. This
corrosion or discoloration might lower solderability or might effect on optical
characteristics.-Please avoid rapid transitions in ambient temperature, especially in high
humidity environments where condensation can occur.
‧ Moisture Proof package
When moisture is absorbed into the SMT package it may vaporize and expand during
soldering. There is a possibility that this can cause exfoliation of the contacts and
damage to the optical characteristics of the LEDs. For this reason, the moisture proof
package is used to keep moisture to a minimum in the package. A package of a moisture
desiccant (silica gel)is inserted into the moisture proof bag-The silica gel changes its
color from blue to pink as it absorbs moisture.
(2)Static Electricity
‧ Static electricity or surge voltage damages the LEDs. It is recommended that a wrist
band or an anti-electrostatic glove and shoe be used when handling the LEDs.
‧ All devices, equipment and machinery must be properly grounded. It is recommended
that measures be taken against surge voltage to the equipment that mounts the LEDs.
‧ When inspecting the final products in which LEDs were assembled, it is recommended
to check whether the assembled LEDs are damaged by static electricity or not. It is easy
to End static-damaged LEDs by a light-on test or a VF test at a lower current (below
lmA).
‧ Damaged LEDs will show some unusual characteristics such as the leak current
remarkably increases, the forward voltage becomes lower, or the LEDs do not light at
the low current. (Criteria : VF>2.0V at IF=0.5mA.)
(3)Heat Generation
‧ Please consider the heat generation of the LED when making the system design that it’s
very importance. The coefficient of temperature increase per input electric power is
effected by the thermal resistance of the circuit board and density of LED placement on
the board, and other components. It is necessary to avoid intense heat generation and
operate within the maximum ratings given in this specification.
‧ The operating current should be decided after considering the ambient maximum
temperature of LEDs.

(4)Others
‧ Care must be taken to ensure that the reverse voltage will not exceed the absolute
maximum rating when using the LEDs with matrix drive.
‧ The LED light output is strong enough to injure human eyes. Precautions must be taken
to prevent looking directly for more than a few seconds. Flashing lights have been
known to cause discomfort in people; you can prevent this by taking precautions during
use. Also, people should be cautious when using equipment that has had LEDs
incorporated into it.
