-3- [ utz - sc0272_ 2 ] 2012/10/02 cautions (1) operating method the ld shall change its forward voltage requirement and optical output power according to temperature change. also, the ld will require more operation current to maintain same output power as it degrades. in order to maint ain output power, use of apc (automatic power control) is recommended, wh ich use monitor feedback to adjust the operation cu rrent. confirm that the optical output power generated by spike current when switching on and off does not ex ceed the maximum absolute rating. also, employ appropriate counterm easures to reduce chattering and/or overshooting in the circuit. (2) static electricity static electricity or electrical surges will reduce and degrade the reliability of the lds. it is reco mmended to use a wrist strap or anti-electrostatic glove when handling the product. (3) absolute maximum rating active layer of lds shall have high current density and generate high electric field during its operat ion. in order to prevent excessive damage, the ld must be operated s trictly below absolute max rating. (4) others nichia lds described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment, communications equipment, measurement instruments a nd household appliances). consult nichias sales st aff in advance for information on the applications in which except ional quality and reliability are required, particu larly when the failure or malfunction of the lds may directly jeopardize life or health (such as for airplanes, aerospace, subme rsible repeaters, nuclear reactor control systems, automobiles, traff ic control equipment, life support systems and safe ty devices). the purchaser must acknowledge that any ld can be f ailed statically and must design its equipments fai l safe design. prior to use of the ld, please confirm that the ld, as de scribed in nichias specifications, meets the life expectancy needs of, and provides the features required by the circuit and a ny related modules, equipment and/or systems. nichia prohibit purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure or design of the ld. the appearance and specifications of the product ma y be modified for improvement without notice. the f ormal specifications must be exchanged and signed by both parties before large volume purchase begins. no unauthorized transmission or reproduction of thi s document, either in whole or in part, is permitte d.
