Safety Precautions
1) The products are designed and produced for application in ordinary electronic equipment (AV equipment,
OA equipment, telecommunication equipment, home appliances, amusement equipment, etc.).
If the products are to be used in devices requiring extremely high reliability (medical equipment,
transport equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment
including car accessories, safety devices, etc.) and whose malfunction or operational error may endanger
human life and sufficient fail-safe measures, please consult with the Company’s sales staff in advance.
If product malfunctions may result in serious damage, including that to human life, sufficient fail-safe
measures must be taken, including the following:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits in the case of single-circuit failure
2) The products are designed for use in a standard environment and not in any special environments.
Application of the products in a special environment can deteriorate product performance. Accordingly,
verification and confirmation of product performance, prior to use, is recommended if used under the
following conditions:
[a] Use in various types of liquid, including water, oils, chemicals, and organic solvents
[b] Use outdoors where the products are exposed to direct sunlight, or in dusty places
[c] Use in places where the products are exposed to sea winds or corrosive gases, including
Cl

, H

S, NH

, SO

, and NO
2
[d] Use in places where the products are exposed to static electricity or electromagnetic waves
[e] Use in proximity to heat-producing components, plastic cords, or other flammable items
[f] Use involving sealing or coating the products with resin or other coating materials
[g] Use involving unclean solder or use of water or water-soluble cleaning agents for cleaning after
soldering
[h] Use of the products in places subject to dew condensation
3) The products are not radiation resistant.
4) The Company is not responsible for any problems resulting from use of the products under conditions not
recommended herein.
5) The Company should be notified of any product safety issues. Moreover, product safety issues should
be periodically monitored by the customer.
●
Precautions Regarding Application Examples and External Circuits
1) If change is made to the constant of an external circuit, allow a sufficient margin due to variations of the
characteristics of the products and external components, including transient characteristics, as well as
static characteristics.
2) The application examples, their constants, and other types of information contained herein are applicable
only when the products are used in accordance with standard methods. Therefore, if mass production is
intended, sufficient consideration to external conditions must be made.

●
Precautions Regarding Foreign Exchange and Foreign Trade Control Law
1) The Company has not determined whether or not the products are considered “a controlled product or
labor ” as specified in the Foreign Exchange and Foreign Trade Control Law.
Accordingly, if exportation of the products, either separately or integrated in another company’s
products, is intended, or giving the products to persons who are not residents is planed, additional steps
are required, based upon the appropriate regulations.
●
Prohibitions Regarding Industrial Property
1) These Specifications contain information related to the Company’s industrial property. Any use of them
other than pertaining to the usage of appropriate products is not permitted. Duplication of these
Specifications and its disclosure to a third party without the Company’s permission is prohibited.
2) Information and data on products, including application examples, contained in these specifications are
simply for reference; the Company does not guarantee any industrial property rights, intellectual property
rights, or any other rights of a third party regarding this information or data. Accordingly, the Company
does not bear any responsibility for:
[a] infringement of the intellectual property rights of a third party
[b] any problems incurred by the use of the products listed herein.
3) The Company prohibits the purchaser of its products to exercise or use the intellectual property rights,
industrial property rights, or any other rights that either belong to or are controlled by the Company, other
than the right to use, sell, or dispose of the products.
●
Precautions on Use of Products
1) Verification and confirmation of performance characteristics of products, after on-board mounting, is
advised.
2) In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse) is
applied, confirmation of performance characteristics after on-board mounting is strongly recommended.
Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state
loading condition may negatively affect product performance and reliability.
3) When a highly active halogenous (chlorine, bromine, etc.) flux is used, the remainder of flux may
negatively affect product performance and reliability.
4) In principle, the reflow soldering method must be used; if flow soldering method is preferred, please
consult with the Company in advance
5) Pay attention to the soldering condition in order to avoid problems due to silver absorption into solder.
6) Be careful when pick up the products with tweezers.
There may be a case that the overcoat and /or the body can be chipped.
7) Soldering tip shall not touch the product when install product manually.
8) Product may be damaged when the impact, such as downfall is given.
●
Precautions Regarding Product Storage
1) Product performance and soldered connections may deteriorate if the products are stored in the following
places:
[a] Where the products are exposed to sea winds or corrosive gases, including Cl
2
, H
2
S, NH
3
, SO
2
,
and NO
2
[b] Where the temperature or humidity exceeds those recommended by the Company
2) The guaranteed period of solder connections and product performance is within one year from shipment
by the Company, provided that the above-mentioned storage conditions have been satisfied.
●
Other Matters
1) Please sign these Specifications and return one copy to the Company.
If a copy is not returned within three months after the issued date specified on the front page of these
Specifications, the Company will consider the Specifications accepted.
2) If any matter related to these Specifications needs to be clarified, discussions shall be held promptly
between the two parties concerned to determine the issue.

* In the items on characteristics, the expression "
±(1.0%
+ 0.05Ω)" is used in the column for
standard values.
However, this is because of dramatic increase in the fluctuation ratio that can be take place in the
low resistance value range and is not meant to supplement the measuring accuracy of the
measuring instruments.
Accordingly, there is a need to increase the design tolerance in the low resistance value range.
