CAUTIONS
1. Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office
equipment, communication equipment and household applications).Consult Liteon’s Sales in advance for
information on applications in which exceptional reliability is required, particularly when the failure or
malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic
control equipment, medical and life support systems and safety devices).
2. Storage
This product is qualified as Moisture sensitive Level 3 per JEDEC J-STD-020 Precaution when handing
this moisture sensitive product is important to ensure the reliability of the product.
The package is sealed:
The LEDs should be stored at 30°C or less and 90%RH or less. And the LEDs are limited to use within
one year, while the LEDs is packed in moisture-proof package with the desiccants inside.
The package is opened:
The LEDs should be stored at 30°C or less and 60%RH or less. Moreover, the LEDs are limited to
solder process within 72hrs. If the Humidity Indicator shows the pink color in 10% even higher or
exceed the storage limiting time since opened, that we recommended to baking LEDs at 60°C at least
24hrs. To seal the remainder LEDs return to package, it’s recommended to be with workable desiccants
in original package.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.

5. Drive Method
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in
parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive
circuit, in series with each LED as shown in Circuit A below.

(A) Recommended circuit.
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics of
those LEDs.
6. ESD (Electrostatic Discharge)
Static Electricity or power surge will damage the LED.
