data sheet pn10226ej02v0ds 14 ps2502-1,-2,-4,ps2502l-1,-2,-4 (4) cautions fluxes avoid removing the residual flux with freon-based and chlorine-based cleaning solvent. 2. cautions regarding noise be aware that when voltage is applied suddenly bet ween the photocoupler?s i nput and output or between collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute maximum ratings. 3. measurement conditions of current transfer ra tios (ctr), which differ according to photocoupler check the setting values before use, since the forward current conditions at ctr measurement differ according to product. when using products other than at the specified forward current, the char acteristics curves may differ from the standard curves due to ctr value variati ons or the like. theref ore, check the characte ristics under the actual operating conditions and thoroughly take variations or the like into cons ideration before use. usage cautions 1. protect against static electricity when handling. 2. avoid storage at a high te mperature and high humidity.

"standard": computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "special": transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "specific": aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. the quality grade of nec semiconductor products is "standard" unless otherwise expressly specified in nec's data sheets or data books, etc. if customers wish to use nec semiconductor products in applications not intended by nec, they must contact an nec sales representative in advance to determine nec's willingness to support a given application. (note) (1) "nec" as used in this statement means nec corporation, nec compound semiconductor devices, ltd. and also includes its majority-owned subsidiaries. (2) "nec semiconductor products" means any semiconductor product developed or manufactured by or for nec (as defined above). ? ? ? ? ? ?
