Please storing in the airtight container with
our desiccant (silica gel)
Baking
・
Bake the product in case of below:
①The
expiration date is passed.
②The
color of indicator (silica gel) turned from blue to colorless or from green to pink. (Even if the product is
within the expiration date.)
Baking Conditions

・
Bake products in reel.
・
Reel and embossed tape are easy to be deformed when baking, so please try not to apply
stress on it.
・
Recommend bake once.
2.Application Methods
2-1. Precaution for Drive System and Off Mode
Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that applies on the
products. If drive by constant voltage, it may cause current deviation of the LED and result in deviation of
luminous intensity, so we recommend to drive by constant current. (Deviation of VF Value will cause deviation of
current in LED.) Furthermore, for off mode, please do not apply voltage neither forward nor reverse. Especially,
for the products with the Ag-paste used in the die bonding, there’ high possibility to cause electro migration
s
and result in function failure.
2-2. Operation Life Span
There’ possibility for intensity of light drop according to working conditions and environments (applied
s
current, surrounding temperature and humidity, corrosive gases), please call our Sales staffs for inquiries about
the concerned application below.
①Longtime
intensity of light life
②On
mode all the time
2-3.Applied Stress on Product
The top of the LED is very soft, which the silicon resin is used as sealing resin. Therefore, please pay attention
to the overstress on it which may influence its reliability.
2-4.Usage
The Product is LED. We are not responsible for the usage as the diode such as Protection Chip, Rectifier,
Switching and so on.
3. Others
3-1. Surrounding Gas
Notice that if it is stored under the condition of acid gas (chlorine gas, sulfured gas) or alkali gas (ammonia), it
may result in low soldering ability (caused by the change in quality of the plating surface ) or optical
characteristics changes (light intensity, chrominance) and change in quality of die bonding (Ag-paste) materials.
All of the above will cause function failure of the products.
Therefore, please pay attention to the storage environment for mounted product (concern the generated gas of
the surrounding parts of the products and the atmospheric environment).
