2.Application Methods
2-1.Color of sealing resin
This product may differ in the color of the resin due to the influence of the material contained in the sealing resin.
There are no problems with the use.
2-2. 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’s high possibility to cause electro migration and result
in function failure.
2-3. About derating
It is considered that derating characteristics will not result in LED chip’s electrical destruction. Even within the
derating, the reliability and luminous life can be affected depending on operating conditions and ambient
environment. So we would be appreciate it if you can confirm with your application again.
2-4. About product life
Depending on operating conditions and environment(applied current, ambient temperature and humidity, corrosive
gas), decreasing of luminosity and change of chromaticity may occur even within the specification conditions.
Please contact our sales office if you use it for the following applications.
ꢀ① It requires long luminosity life
ꢀ② It is always lit
2-5.Applied Stress on Product
No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, please pay attention
to the overstress on it which may influence its reliability.
2-6.Usage
The product is LED. We are not responsible for the usage as the diode such as protection chip, rectifier,
switching and so on.
