Precautions for Safety

●

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 ROHM 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

, H2S, NH3, SO2, and NO2

Cl

2

[d] Use in places where the products are exposed to static electricity or electromagnetic waves
[e] Use in environment subject to strong vibration and impact.
[f] Use in proximity to heat-producing components, plastic cords, or other flammable items
[g] Use involving sealing or coating the products with resin or other coating materials
[h] Use of the products in places subject to dew condensation

3) The products might receive the radio wave interference from electronic devices such as Wireless LAN
devices, Bluetooth devices, digital cordless telephone, microwave oven and so on that radiate
electromagnetic wave.

4) The products are not radiation resistant.

5) Verification and confirmation of performance characteristics of products, after on-board mounting, is
advised.

6) Confirm that operation temperature is within the specified range described in product specification.

7) Failure induced under deviant condition from what defined in the product specification can not be

guaranteed.

8) This product is a specification to radiate the radio wave. It is necessary to acquire the attestation of

decided Radio Law of each region used to use the equipment that radiates the radio wave.

Please inquire about the attestation of Radio Law that this product acquires.

9) When product safety related problems arises, please immediately inform to ROHM, and consider

technical counter measure.

●Precautions for Reference 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 reference circuit 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.

Precaution for Electrostatic

●

This product is Electrostatic sensitive product, which may be damaged due to Electrostatic discharge.

Please take proper caution during manufacturing and storing so that voltage exceeding Product maximum
rating won't be applied to products. Please take special care under dry condition (Grounding of human
body / equipment / solder iron, isolation from charged objects, setting of Ionizer, friction prevention and
temperature / humidity control etc.)

● Precaution for Storage / Transportation

1) Product performance and connector mating 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

and NO

2

[b] Where the temperature or humidity exceeds those recommended by the Company
Temperature: 5℃～40℃, Humidity 40%～60%
[c] Storage in direct sunshine or condensation.
[d] Storage in high Electrostatic.

2) Even under ROHM recommended storage condition, connector mating of products over 1 year old

may be degraded.

3) Store / transport cartons in the correct direction, which is indicated on a carton as a symbol, otherwise

bent leads may occur due to excessive stress applied when dropping of a carton..

Precaution for Product Label

●

QR code printed on ROHM product label is only for internal use, and please do not use at customer site.

It might contain a internal part number that is inconsistent with an product part number.

Precaution for Disposition

●

When disposing products please dispose them properly with a industry waste company.

Precaution for Foreign Exchange and Foreign Trade Act

●

Note: Since concerned goods are fallen under controlled goods prescribed by Foreign exchange and Foreign

trade act, the permission based on the act is necessary in case of export. Please follow the necessary
procedures based on relevant laws and regulations when end goods, which were manufactured by your
company with the concerned goods, are brought to foreign countries or nonresident.
