CAUTIONS
1. Application limitation
The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment,
communication equipment and household application.) Consult Liteon’s sales in advance for information on
application in which exceptional quality and reliability are required, particularly when the failure or malfunction
of the LEDs may directly jeopardize life or health (such as airplanes, automobiles, traffic control equipment, life
support system and safety devices).
2. Storage
After being shipped from Liteon the LEDs should be kept at 30°C or less and 70%RH or less.
The LEDs should be used within 3 months. They can be stored for a year in a sealed container with a nitrogen
atmosphere and moisture absorbent material. Please avoid rapid transitions in ambient temperature in high
humidity environments where condensation may occur.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED.
4. Forming & Mounting
When forming a lead, the leads should be bent at a point at least 3mm from the base of epoxy bulb. Do not use
the base of the leadframe as a fulcrum during forming. Lead forming must be done before soldering at normal
temperature. When mounted through hole type LED lamp, avoid the occurrence of residual mechanical stress
due to clinching.
5. Soldering
When soldering, leave a minimum of 2mm clearance from the resin to the soldering point.
Dipping the resin into the solder must be avoided.
Do not apply any stress to the lead frame during soldering while the LED is at high temperature.

*The material of hook type Housing is very sensitive of soldering temperature. Any increase of soldering
temperature might seriously result in serious melting of the housing.
6. Drive Method
LED, a current operated device, requires specific current limit incorporated into the driving circuit. The current
control can be achieved by using a resistor in series with the LED. In order to prevent to exceed the allowed value
of 40% over desired forward current, the resistor should be well chosen for possible voltage variation. Two
possible circuit designs are shown below. The model A is recommended, and the model B will probably result in
uneven brightness between LEDs because of the Vf-If characteristics of LEDs.

7. ESD (Electrostatic Discharge)
Static electricity discharge or power surge will damage the LED. When handling the LED, it is highly
recommended to use a conductive wrist band or anti-electrostatic glove. All devices, equipment and machinery
must be properly grounded.
