Notes: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve. 2. 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity. 3. The dominant wavelength, d is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 4. Caution in ESD: Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-electrostatic glove when handling the LED. All devices, equipment and machinery must be properly grounded.

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 opening the package. The LEDs should be kept at 30C or less and 70%RH or less. The LEDs should be soldered within 168 hours(7 days) after opening the package. If unused LEDs remain, they should be stored in moisture proof package, such as sealed containers with packages of moisture absorbent material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again. If LEDs have exceeded the storage time, baking treatment should be performed with 605C more than 24 hours. 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 Pre-heat Pre-heat time Peak temperature Soldering time Soldering iron Wave soldering Pre-heat Pre-heat time Solder wave Soldering time 100C Max. 60 sec. Max. 260C Max. 10 sec. Max. Temperature 300C Max. 120~150C 120 sec. Max. Soldering time 3 sec. Max. (one time only) 260C Max. 5 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.
