(Common precautions for Fixed Resistors)
? When using our products， no matter what sort of equipment they might be used for， be sure to make a written
agreement on the specifi cations with us in advance. The design and_specifi cations in this catalog are subject
to change without prior notice.
? Do not use the products beyond the specifi cations described in this catalog.
? This catalog 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 the loss of human life or other signifi cant damage， such as damage to
vehicles (au to mo bile， train， vessel)， traffi 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 equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault
(1) Precautions for use
? These products are designed and_manufactured for general and_stan dard use in general elec tron ic
equipment (e.g. AV equipment， home electric ap pli anc es， offi ce equipment， information and_com mu ni ca tion
equipment)
? These products are not intended for use in the following special conditions. Be fore using 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 components are more sensitive to ESD environment.
5. Electromagnetic Environment
Avoid any environment where 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 com po nents. Do not mount or place heat-generating com po nents or
infl ammables， such as vinyl-coated wires， near these products .
? Note that non-cleaning solder， halogen-based highly active fl ux， or water-soluble fl ux may deteriorate the
performance or reliability of the products.
? Carefully select_a fl 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 res i dues. 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 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 within 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 deteriorated， and_the packaging materials (e.g. tap ing ma te ri als)
may be de formed 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.
