nichia sts-da1-3164 9 cautions (1) storage the products should be stored in an air tight container with desiccant (silica gel) at 30c or less and 70% rh or less. to avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly. the led incorporated in the product is silver plated. customer is advised to store properly the products in controlled ambient as exposure to a corrosive environment might cause the plated metal parts of the product to tarnish, which might leads to adverse effects on optical characteristics. (2) handling precautions do not expose the product to shock. failure to comply might affect on its characteristics. (3) electrostatic discharge (esd) the products are sensitive to static electricity or su rge voltage. esd can damage a die and its reliability. when handling the products, the following measures against electrostatic discharge are strongly recommended: eliminating the charge grounded wriststrap, esd footwear, clothes, and floors grounded workstation equipment and tools esd table/shelf mat made of conductive materials the customer is advised to check if the leds are damaged by esd when performing the characteristics inspection of the leds in the application. damage can be detected with a forwar d voltage measurement or a light-up test at low current. esd damaged leds may have a current flow at a low voltage or no longer illuminate at a low current. failure criteria: v f <2.0v at i f =0.5ma (4) eye safety the international electrical commission (iec) publis hed in 2006, iec 62471:2006 photobiological safety of lamps and lamp systems which includes leds within its scope. meanwhile leds were removed from the scope of the iec 60825-1:2007 laser safety standard, the 2001 edition of which included led sources within its scope. however, keep it mind that some countries and regions ha ve adopted standards based on the iec laser safety standard iec 60825-1:2001 which includes leds within its scope. follo wing iec 62471:2006, most of nichia leds can be classified as belonging to either exempt group or risk group 1. especially a high-power led, that emits light containing blue wavelengt hs, may be in risk group 2. great care should be taken when viewing directly the led driven at high current or the led with optical instruments, which grea tly increase the hazard to your eyes. viewing a flashing light may cause eye discomfort. when incorporating the led into your product, precaution should be taken to avoid adverse e ffect on human body caused by the light stimulus. (5) others this product is designed to be used fo r calibration. do not use this product fo r any other purposes or other applications. the customer shall not reverse engineer by disassembling or analysis of the leds without having prior written consent from nichia. when defective leds are found, the customer shall inform nichia directly before disassembling or analysis. when a customer purchases this product, the customer and nichia shall agree the official specification of the supplied product s. specifications and appearance subject to change for improvement without notice.
