? ex2 ? safety precautions (common precautions for emi filters, fuses, and sensors[mr elements]) when using our 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 catalog explains the quality and performance of the products as individual components. before 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 the loss of human life or other signi? cant dam age, such as damage to vehicles (automobile, train, vessel), traf? c lights, medical equipment, aerospace equipment, electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment. ? systems equipped with a protection circuit and a protection device ? systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a sin gle fault (1) precautions for use these products are designed and manufactured for general and standard use in general elec tron ic equipment (e.g. av equipment, home electric appliances, of? ce equipment, information and communication e quipment) these products are not intended for use in the following special conditions. before using the products, carefully 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 wher e strong electromagnetic waves exist. 6. in an environment where these products cause dew condensation 7. sealing or coating of these products or a printed circuit board on which these products are mounted, with resin or other materials these products generate joule heat when energized. carefully position these products so that their heat will not affect the other components. carefully position these products so that their temperatures will not exceed the category temperature range due to the effects of neighboring heat-generating components. do not mount or place heat-generating components or in? ammables, such as vinyl-coated wires, near these products (except thermal cutoffs). note that non-cleaning solder, halogen-based highly active ? ux, or water-soluble ? ux may deteriorate the performance or reliability of the products. carefully select a ? ux cleaning agent for use after soldering. an unsuitable agent may deteriorate the performance or reliability. in particular, when using water or a water-soluble cleaning agent, be careful not to leave water residues. otherwise, the insulation performance may be deteriorated. (2) precautions for storage the performance of these products, including the solderability, is guaranteed for a year from the date of ar riv al at your company, provided that they remain packed as they were when delivered and stored at a tem per a ture of 5 c to 35 c and a relative humidity of 45 % to 85 %. (micro chip fuses: guaranteed for 6 months from the date of arrival at your company) the performance of emi filters is guaranteed for 6 months or a year from the out go ing inspection date indicated on the packages, provided that they are stored at a temperature of -5 c to +40 c and a relative humidity of 40 % to 60 %. check the guarantee period in the speci? cations. the performance of thermal cut offs is guaranteed for a year from the outgoing inspection date indicated on the packages, provided that they are stored at a temperature of -10 c to +40 c and a relative humidity of 30 % to 75 %. even within the above guarantee periods, do not store these products in the following conditions. otherwise, their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping materials) may be deformed or deteriorated, 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 markings include the product number, quantity, and country of origin. in principle, the country of origin should be indicated in english. feb. 2006
