■ Precaution for Use
1) For over-current-proof function, customers are recommended to apply resistors to prevent
sudden change of the current caused by slight shift of the voltage.
2) This device should not be used in any type of fluid such as water, oil, organic solvent,
etc.
When washing is required, IPA is recommended to use.
3) When the LEDs illuminate, operating current should be decided after considering the
ambient maximum temperature.
4) LEDs must be stored in a clean environment.
If the LEDs are to be stored for 3 months or more after being shipped from SEMCO,
they should be packed by a sealed container with nitrogen gas injected.
(Shelf life of sealed bags : 12 months, temp. 0~40℃, 20~70%RH)
5) After storage bag is open, device subjected to soldering, solder reflow, or other high
temperature processes must be:
a. Mounted within 168 hours (7 days) at an assembly line with a condition of no
more than 30℃/60%RH,
b. Stored at <10% RH.
6) Repack unused Products with anti-moisture packing, fold to close any opening and then
store in a dry place.
7) Devices require baking before mounting, if humidity card reading is >65% at 23±5℃.
8) Devices must be baked for 24hours at 65±5℃, if baking is required.
9) The LEDs are sensitive to the static electricity and surge. It is recommended to use a
wrist band or anti-electrostatic glove when handling the LEDs.
If voltage exceeding the absolute maximum rating is applied to LEDs, it may cause
damage or even destruction to LED devices.
Damaged LEDs may show some unusual characteristics such as increase in leak
current, lowered turn-on voltage, or abnormal lighting of LEDs at low current.
