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

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

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.
