nichia sts-da1-1237b 8 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 controll ed ambient as exposure to a co rrosive environment might cause the plated metal parts of the product to tarnish, which might leads to adverse effects on optical characteristics. (2) handling precautions the led used in this product employs silic one as encapsulating resin. do not touch the encapsulant as the encapsulant is soft and easy to attract dirt. failure to comply might have adverse e ffects on characteristics, and, in the worst case scenario, lea d to catastrophic failure. 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. an esd event ma y damage its die or reduce its reliability performance. when handling the produc ts, measures against electro static discharge, including the followings, are strongly recommended. eliminating the charge; wrist strap, esd footwear and garments, esd floors grounding the equipment and tools at workstation esd table/shelf mat (conductive materials) proper grounding techniques are required for all devices, eq uipment and machinery used in the assembly of the products. if tools or equipment contain insulating materials, such as glass or plastic, proper measures against electro static discharge , including the followings, are strongly recommended. dissipating the charge with conductive materials preventing the charge generation with moisture neutralizing the charge with ionizers during characteristics inspection of this product, it should be checked wh ether the led is not damaged by esd. such damage can be detected during forw ard voltage measurement or light up test at low current. (the recomm ended current is 6ma or lower) esd-damaged leds may have a current flow at low voltage, or no longer light up at low current. failure criteria: v f <2.0v at i f =3ma (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. the appearance and specifications of the produc t may be modified for improvement without notice.
