12. Precaution for Use
(1) Storage
LEDs must be stored at clean atmosphere. If the LEDs are stored for 3 months or more
after shipment from SSC, storage in a sealed container with a nitrogen atmosphere is
recommended. To avoid absorption of moisture, it is recommended to store in a dry box
(or a desiccator) with a desiccant.
* Shelf Life : 12 months at < 40ºC and 90%RH
(2) Attention after open.
LED is correspond to SMD, when LED be soldered dip, interfacial separation may affect
the light transmission efficiency, causing the light intensity to drop. After opened and
mounted the soldering shall be quickly.
* Within 672 hours at factory conditions of equal to or less than 30ºC/60%RH, or
Stored at < 10% RH
(3) Repack unused products with anti-moisture packing, fold to close any opening and
then store in a dry place.
(4) In the case of change color of indicator on desiccant, components shall be dried
10-12hr at 60±5ºC.
(5) When the LED is operating, the driving current should be determined after considering
the maximum ambient temperature requirements.
(6) When using multiple LEDs, It is recommended to connect a resistor on each LED.
Otherwise, LEDs may vary due to variation in forward voltage of the LEDs.
(7) The driving circuit must be designed to allow forward voltage only when it is ON or
OFF. If the reverse voltage is applied to LED, migration can be generated resulting
in LED damage
(8) Any mechanical force or excessive vibration should be avoided during temperature
cooling process to normal temperature after reflow.
(9) Rapid cooling shall be avoided.
(10) LED should not be placed on a flexible area on the PCB.
(11) 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.
(12) Anti radioactive ray design is not considered for the products.
(13) Damage prevention from ESD or Surge.
It is highly recommended to use the wrist-band or anti electrostatic gloves when handling
the LED’s All devices, equipments and machines mush be properly grounded
(14) The appearance and specifications of the product may be modified for improvement
without notice.
