6) Precaution for the Mounting
Do not apply force to the plastic part of the LED under high-temperature conditions.
To avoid damaging the LED plastic, do not apply friction using hard materials.
During installing the PCB in product, ensure that the device does not came into
contact with other components
7) Recommended Operating Current
Operating current is optimized on test conditions of grouping parameter.
We recommend the operating current of each LED more than 2mA.
If the LED must be operated less than 2mA, special care should be taken to insure that the
intensity of illumination.is not uniformed by deviation of the IF upon low operating voltage.

11. Precaution for use
-. This device should not be used in any type of fluid such as water, oil, organic solvent, etc.
When washing is required, IPA should be used.
-. When the LEDs are illuminating, operating current should be decided after considering the
ambient maximum temperature.
-. In order to avoid the absorption of moisture, it is recommended to less 12 month store at 40℃,
90%RH or below environment
-. After opening the moisture proof packing, the LED’s should be kept at 5℃~30℃, 60%RH or
below.
The LEDs must be soldered within seven days(168 hours) after opening the moisture-proof
packing.
If the LEDs remains after soldering , it should be stored into moisture proof container.
-. Repack unused Products with anti-moisture packing, fold to close any opening and then store in
a dry place.
-. If upon opening, the moisture indicator card shows humidity 30% or above (Color of indication
changes to pink) or the expiration date has passed, the device should be baked in taping with reel
using the conditions of 65±5℃, 12~24hours.
After baking, use the baked devices within 72hours, but perform baking only once.
-. Repeated baking can cause the peeling strength of the taping to change, then leads to trouble in
mounting. Furthermore, prevent the devices from being destructed against static electricity for
baking of it.
-. The appearance and specifications of the product may be modified for improvement without
notice.
-. If the packing material of laminate would be broken, the hermeticity would deteriorate. Therefore.
do not throw or drop the packed devices..
-. This LEDs is sensitive to the electrostatic and surge,
It is recommended to use a wrist band or anti-electrostatic glove when handling the LEDs.
-. If over-voltage which exceeds the absolute maximum rating is applied to LEDs, It will cause
damage LEDs and result in destruction.
-. Damaged LEDs will show unusual characteristics such as leak current remarkably increase,
turn-on voltage becomes lower and the LEDs get unlight at low current.
-. It is better not to use different rank LEDs.
If use mixed rank, could not attain your object for highest quality of products.
