No packing unit 1 tape ever contains more than one forward voltage group. These values measured by Optical Spectrum Analyzer of LG Innotek Co., Ltd and tolerances are followings as below - Luminous Intensity(Iv) : 20%, Forward Voltage(V F ) : 0.1V, Dominant Wavelength(λd) : 2nm

7 7 / Package and Marking of Products 8-1. Taping Outline Dimension ( Unit : mm ) Packing Materials : - Reel : Conductive PS (Black) - Emboss Tape : Conductive PS (Black) - Cover Tape : Conductive PET Base 8-2. Package Products are packed in one bag of 5,000 pcs (one taping reel) and a label is affixed on each bag specifying Model, Rank, Quantity and Run number. Label A (Model, Rank, Quantity, Run number) - Package : damp-proof package made of aluminum

9 9 / Packing Specifications Reeled products (numbers of products are 5,000 pcs) packed in a seal off aluminum moisture-proof bag along with desiccants (Silica gel). Five aluminum bags (total maximum number of products are 25,000 pcs) packed in an inner box and Six inner boxes are put into an outer box.

11 11/ Cautions on use 9-1.Circuit Layout In general, The LEDs have a variation of forward voltage. Using LEDs with different forward voltages in a circuit with on resistor for the complete circuit causes different forward currents for each LED. This may lead to a variation in brightness. To avoid brightness variation of LEDs, the use of matrix circuit with one resistor for each LED is recommended Over-current-proof Customer must apply resistors for protection, others slight voltage shift will cause big current change ( Burn out will happen ) For the Storage - Proper temperature and RH conditions for storage are : 5 ~35, RH 60%. - Do not open moisture-proof bag before the products are ready to use. - Store products in a moisture-proof bag with a desiccant(silica gel) after open. - These products should be used within 168 hours after opening the bag based upon storage condition. - These products must be baked to remove moisture before using them if the Silica gel loses its blue color. Conditions for baking are 605, 20% (RH) and 24 hours maximum. (For reeled status without bag) - Considering the tape life, we suggest our customers to use our products within a year(from production date) 9-4. LG Innotek will not be held responsible for any damage to the user that may result from accidents or any other reasons during operation of the user s unit if use to exceed the absolute maximum ratings, or not keep the matters that demand special attention.
