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.
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED.
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 as figure shown here.
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.
Recommended soldering condition
LED is a current operated device, and therefore, requires some kind of current limiting incorporated into the
drive circuit. This current limiting typically takes the form of a current limiter resistor placed in series with
the LED. Consider worst case voltage variations that could occur across the current limiting resistor.
The forward current should not be allowed to change by more than 40% of its desired value.
(A) Recommended circuit.
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).
(B) The difference of brightness between LEDs could be found due to the Vf-If characteristics of LED
