◆ Cautions
1、Package
When moisture is absorbed into the 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.
So the moisture proof package is used to keep moisture to a minimum in the package.
2、Storage
•Before opening the package
a. Avoid the absorption of moisture, we recommended to store the LEDs in a dry box(or desiccator) with a
desiccant . Otherwise, store them in the following environment: Temperature : 5℃~30℃,Humidity :
60%max.
b. The products should be used in 3 months. It is recommended that the LEDs be used as soon as possible.
•After opening the package
a. Soldering should be done right after opening the package(within 24Hrs).
b. Keeping of a fraction
-sealing
-Temperature : 5 ~ 30℃,Humidity : less than 30%
c. If the package has been opened more than 1week or the color of desiccant changes,
Components should be dried for 10-12hr at 60±5℃
3、Lead Forming
•When the lead forming is required before soldering , care must be taken to avoid any bending
and mechanical stress. The stress to the base may damage the LEDs.
•When mounting the LEDs onto a PCB, the holes on the circuit board should be exactly aligned with
the leads of the LEDs.
•It is recommended that tooling made to precisely form and cut the leads to length rather than
rely on hand operating.
4、The LED electrode sections are comprised of a gold plated. The gold surface may be affected by
environments which contain corrosive gases and so on. Please avoid conditions which may cause the LED to
corrode or discolor. This corrosion or discoloration may cause difficulty during soldering operations. It is
recommended that the User use the LEDs as soon as possible.
5、Please avoid rapid transitions in ambient temperature, especially in high humidity environments where
condensation can occur.
6、Static Electricity
6.1、These products are sensitive to static electricity charge, and users are required to handle with care.
Particularly, if an current and or voltage which exceeds the Absolute Maximum Rating of Products is applied,
the overflow in energy may cause damage to, or possibly result in electrical destruction of, the Products. The
customer is requested to take adequate countermeasures against static electricity charge and surge when
handling Products.
6.2、Proper grounding of Products , use of conductive mat, conductive working uniform and shoes, and
conductive containers are effective against static electricity and surge.

6.3、Ground low-resistance areas where the product contacts, such as metal surfaces of the work platform,
with a conductive mat (surface resistance 106-108 Ω ).
6.4、A tip of soldering iron is requested to be grounded. An ionizer should also be installed where risk of
static generation is high.
7、Circuit Protection
Below the zener reference voltage VZ, all the current flows through LED and as the voltage rises to VZ,
the zener diode “breakdown”. If the voltage tries to rise above VZ current flows through the zener branch to
keep the voltage at exactly VZ.
When the LED is connected using serial circuit, if either piece of LED is no light up but current can not
flow through causing others to light down. In new design, the LED is parallel with zener diode, if either piece
of LED is no light up but current can flow through causing others to light up.
◆ Notes:
1、Above specification may be changed without notice. We will reserve authority on material change for
above specification.
2、When using this product, please observe the absolute maximum ratings and the instructions for the
specification sheets. We assume no responsibility for any damage resulting from use of the product which
does not comply with the instructions included in the specification sheets.
