8. Cautions
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).
Storage
This product is qualified as Moisture Sensitive Level 4 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
o
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
o
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 be with workable
desiccants in original package.
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.
