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 as figure shown here. 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. Recommended soldering condition Soldering iron Temperature Soldering time 300°C Max. 3 sec. Max. (one time only) Wave soldering Pre-heat Pre-heat time Solder wave Soldering time 100°C Max. 60 sec. Max. 260°C Max. 10 sec. Max. 6. Drive Method 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. Circuit model A LED Circuit model B LED (A) Recommended circuit. (B) The difference of brightness between LEDs could be found due to the Vf-If characteristics of LED Part No. : LTL2H3SEK-032A / LTL2H3SYK-032A BNS-OD-C131/A4 Page : 8 of 9 LITE-ON TECHNOLOGY CORPORATION Property of Lite-On Only 7. ESD (Electrostatic Discharge) Static Electricity or power surge will damage the LED. Use of a conductive wrist band or anti- electrostatic glove is recommended when handling these LED. All devices, equipment and machinery must be properly grounded. 8. Reliability Test Classification Test Item Test Condition Duration / Cycle Room Temp.
