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

The storage ambient for the LEDs should not exceed 30°C temperature or 70% relative

humidity.

It is recommended that LEDs out of their original packaging are used within three

months.

For extended storage out of their original packaging, it is recommended that the LEDs

be stored in a sealed container with appropriate desiccant or in desiccators with nitrogen

ambient.

3. Cleaning

Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.

4. Lead Forming & Assembly

During lead forming, the leads should be bent at a point at least 3mm from the base of

LED lens.

Do not use the base of the lead frame as a fulcrum during forming.

Lead forming must be done before soldering, at normal temperature.

During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.

5. Soldering

When soldering, leave a minimum of 2mm clearance from the base of the lens to the

soldering point. Dipping the lens into the solder must be avoided.

Do not apply any external stress to the lead frame during soldering while the LED is at high

temperature.
