(2) we take no responsibility for troubles caused by the produc t usage that is not specified in this specification. (3) in advance-notification to us is required in case yo u demand high reliability in the resistors because there is a possibility that a trouble or a failure in our resistor whic h is used in your transportation units (e.g. trains, cars, ships, traffic signal equipment etc.), ocean floo r-equipment, medical equipment, aerospace equipment, electrothermal goods, combustion and gas equipment, power station control equipment, information control equipment, rotating equipment, disaster and crime pr eventive equipment, various safety devices, and the equivalent equipment may cause critical damage occurrence such as loss of life or property. in addition, use fail-safe design as mentioned bel ow for preventing extensive damage and for ensuring the safety: *ensure safety by the system in which the protective circuits and/or protective equipment are installed. *ensure safety by the system in which a single failure does not cause unsafety by installing such as redundant circuits. (4) when a dogma shall be occurred about safety fo r this product, be sure to inform us rapidly, operate your technical examination. (5) the product is designed to use in general standard applications of general electric equipment (av products, household electric appliances, office equipment, information and communication equipment, etc.); hence, it do not take the use under the following special environments into consideration. accordingly, the use in the following special environments, and such environmental conditions may affect the performance of the product ; prior to use, verify the performa nce, reliability, etc. thoroughly. 1) use in liquids such as water, oil, chemical, and organic solvent. 2) use under direct sunlight, in outdoor or in dusty atmospheres. 3) use in places full of corrosive gases such as sea breeze, cl 2 , h 2 s, nh 3 , so 2 , and no x . 4) use in environment with large static electricity or strong electromagnetic waves or strong radial ray. 5) where the product is close to a heating component, or where an inflammable such as a polyvinyl chloride wire is arranged close to the product. 6) where the resistor is sealed or coated with resin etc. 7) where solvent, water, or water-soluble detergent is used in cleaning free soldering and in flux cleaning after soldering. (pay particular attention to water-soluble flux.) 8) use in such a place where the product is wetted due to dew condensation. (6) if transient load (heavy load in a short time) like pulse is expected to be applied, carry out evaluation and confirmation test with re sistors actually mounted on your own board. when the load of more than rated power is applied under the load condition at steady state, it may impair performance and/or reliability of resistor. never exceed the rated power and rated voltage. temperature of resistors may become high even with specified conditions. please confirm safety of heat from resistors on print circuit boar d and components around them. when the product shall be used under special condition, be sure to ask us in advance. (7) halogen type (chlorine type, bromine type, etc.) or other high-activity flux is not recommended as the residue may affect performance or reliability of resistors. strong acid flux, water soluble-flux and flux including fluorine ion shall not be used. (8) when soldering with soldering iron, never touch the body of the chip resistor with a tip of the soldering iron. when using a soldering ir on with a tip at high temperature, solder for a time as short as possible. (three seconds or less up to 350 deg.c) (9) avoid physical shock to the resistor and nipping of the resistor with hard tool (a pair of pliers or tweezers) as it may damage protective film or the body of resistor and may affect resistor?s performance. (10) avoid immersion of chip resistor in solvent for long time. use solvent after the effect of immersion is confirmed.
