LITE-ON TECHNOLOGY CORPORATION Property of Lite-On Only 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 Before opening the package : The LEDs should be kept at 30°C or less and 85%RH or less. The LEDs should be used within a year. After opening the package : The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be soldered within 168 hours(7 days) after opening the package. 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. Soldering Do not apply any stress to the lead frame during soldering while the LED is at high temperature. Recommended soldering condition Reflow soldering Soldering iron Wave soldering Pre-heat 120~150°C Temperature 300°C Max. Pre-heat 100°C Max. Pre-heat time 120 sec. Max. Soldering time 3 sec. Max. Pre-heat time 60 sec. Max. Peak temperature 240°C Max. (one time only) Solder wave 260°C Max. Soldering time 10 sec. Max. Soldering time 10 sec. Max. 5. 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 Circuit model B LED LED (A) Recommended circuit. (B) The difference of brightness between LEDs could be found due to the Vf-If characteristics of LED.
