carbon film resistors design and speci? cations are each subject to change without notice. ask factory for the current technical speci? cations before purchase and/or use. should a safety concern arise regarding this product, please be sure to contact us immediately. safety precautions the following are precautions for individual prod ucts. please also refer to the precautions common to fixed resistors shown on page er3 of this catalog. 1. keep th e rated power and ambient tem per a ture within the speci ed derating curve. * when positioning and mounting carbon film resistors (hereafter called the resistors), make al low ance for the effect of heat generated through cl ose contact between th e resistors and neigh bor ing com po nents and for the temperature rise of adjacent heat-generating com po nents. 2. if a transien t load (heavy load in a short time) like a pulse is expe cted to be applied, check and evaluate the operations of the re sis tors when inst alled in your products be fore use. when app lying pulses to the resistors, keep the pulse peak within the rated voltage. 3. when the resistor s' protective coat ings are chipped, awed, or remove d, the char ac ter is tics of the resistors may be impaired. take special care not to apply mechanical shock during automatic mounting or cause dam age during handling of the boards with the resistors mounted. 4. ultrasonic cleaning may cut the lead wire due to resonance. try and check it before use. 5. flame-retardant type 1)take special care in handling the ame-retardant type because it is covered with a special coating and is therefore by more sus cep ti ble to external shock and solvent damage than other regular types of the resistors. 2)the external coating used for the ame-retardant type is not resistan t to solvent. take great care in using solvent. if problems are anticipated, then take appropriat e preventive measures, such as mounting the resistors after solvent is used. feb. 2006
? er3 ? safety precautions (common precautions for fixed resistors) when using ou r products, no matter what sort of equipment they might be used for, be sure to make a written agreement on the speci? cations with us in advance. the design and speci? cations in this catalog are subject to change without prior notice. do not use the products beyond the speci? cations described in this catalog. this cata log explains the quality and performance of the products as individual components. be fore use, check and evaluate their operations when installed in your products. install the following systems for a failsafe design to ensure safety if these products are to be used in equip ment where a defect in these products may cause th e loss of human life or other signi? cant damage, such as damage to vehicles (au to mo bile, train, vessel), traf? c lights, medical equipment, aerospace equipment, elec tric heating ap pli anc es, com bus tion/gas equipment, rotating equipment, and disaster/crime prevention equip ment. ? systems equipped with a protection circuit and a protection device ? systems equip ped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault (1) precauti ons fo r use these products are designed and manufactured for general and stan dard use in general elec tron ic equipment (e.g. av equipm ent, home el ectric ap pli anc es, of? ce equipment, information and com mu ni ca tion equipment) these products are not intended for use in the following special conditions. be fore u sing the products, care ful ly check the effects on their quality and performance, and determine whether or not they can be used. 1. in liquid, such as water, oil, chemicals, or organic solvent 2. in direct sunlight, outdoors, or in dust 3. in salty air or air with a high concentration of corrosive gas, such as cl 2 , h 2 s, nh 3 , so 2 , or no 2 4. electric static discharge (esd) environment these components are sensitive to static electricity and can be damaged under static shock (esd). please take measures to avoid any of these environments. smaller componen ts are more sensitive to esd environment. 5. electromagnetic environment avoid any enviro nment where stro ng electromagnetic waves exist. 6. in an environment where these pr oducts cause dew condensation 7. s e a li n g o r c o ating of these products or a printed circuit board on which thes e products are mounted, with resin or othe r materials these products generate joule heat when energized. carefu lly position th ese products so that their heat will not affect th e other components. carefully position thes e products so that their temperatures will not exceed the category temperature range due to the effect s of neighboring heat-generating com po nents. do not mount or place heat-generating com po nents or in? ammables, such as vinyl-coated wires, near these products . note that non- cleaning solder, halogen-based highly active ? ux, or water-soluble ? ux may dete riorate the performance or reliab ility of the products. carefully select a ? ux cleaning agent fo r use after soldering. an unsuit able agent may deteriorate the performance or reliability. in particular, when using water or a water-soluble cleaning agent, be careful not to leave water res i dues. otherwise, the insulation performance may be deteriorated. (2) precaution s for storage the performance of these products, including the solderability, is guaran teed fo r a year from the date of arrival at your company, provided that they remain packed as they were when delivered and stored at a temperature of 5 c to 35 c and a relative humidity of 45 % to 85 %. even wi thin the above guarantee periods, do not store these products in the fol low ing conditions. otherwise, their elec tri cal performance and/or solderability may be dete riorated, and the packaging materials (e.g. tap ing ma te ri als) may be de formed or dete riorated, resulting in mounting failures. 1. in salty air or in air with a high concentration of corrosive gas, such as cl 2 , h 2 s, nh 3 , so 2 , or no 2 2. in direct sunlight package ma rkings include the product number, quantity, and country of origin. in principle, the country of origin should be indicated in english. feb. 2006
