Precautions on Use of ROHM Power Module
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
Cl2, H2S, NH3, SO2, and NO2
[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 othe 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 Example 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. Please be informed that the Company has not conducted investigations on whether
or not particular changes in the application examples or external circuits would result in the infringement
of patent rights of a third party.
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.
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.

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.
