Notice
● Precaution on using ROHM Products
1) Our Products are designed and manufactured for application in ordinary electronic equipment (such as
AV equipment, OA equipment, telecommunication equipment, home electronics appliances, amusement
equipment, etc.). If you intend to use our Products in devices requiring extremely high reliability (such as
medical equipment, transport equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers,
fuel controllers, car equipment including car accessories, safety devices, etc.) and whose malfunction or
failure may cause loss of human life, bodily injury or serious damage to property (“Special
Applications”), please consult with the ROHM sales representative in advance. Unless otherwise agreed
in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any damages,
expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for
Specific Applications.
2) ROHM designs and manufactures its Products subject to strict quality control system. However,
semiconductor products can fail or malfunction at a certain rate. Please be sure to implement, at your own
responsibilities, adequate safety measures including but not limited to fail-safe design against the physical
injury, damage to any property, which a failure or malfunction of our Products may cause. The following
are examples of safety measures.
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3) Our Products are designed and manufactured for use under standard conditions and not under any special
or extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in
any way responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s
Products under any special or extraordinary environments or conditions. If you intend to use our Products
under any special or extraordinary environments or conditions (as exemplified below), your independent
verification and confirmation of product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or
dust
[c] Use of our Products in places where the Products are exposed to sea winds or corrosive gases,
including Cl2, H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or
electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other
flammable items
[f]Sealing or coating our Products with resin or other coating materials
[g] Use of the Products in places subject to dew condensation
4) The Products are not subject to radiation-proof design.
5) Please verify and confirm characteristics of the final or mounted products in using the Products.
6) Confirm that operation temperature is within the specified range described in the product specification.
7) ROHM shall not be in any way responsible or liable for failure induced under deviant condition from
what is defined in this document.
8) This Product may be subjected to radio wave interference from other equipment emitting radio waves.
9) This Product emits radio waves due to the specification. To use equipment emitting radio waves,
certification under the Radio Act should be obtained by region in which the Product is used. For the
standards for certification under the Radio Act to be obtained for the use of this Product, separately
contact your ROHM representative.

Notice
● Precaution for Mounting / Circuit board design
1) When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively
affect product performance and reliability.
2) In principle, the reflow soldering method must be used.
● Precautions Regarding Application Examples and External Circuits
1) If change is made to the constant of an external circuit, please allow a sufficient margin considering
variations of the characteristics of the Products and external components, including transient
characteristics, as well as static characteristics.
2) You agree that application notes, reference designs, and associated data and information contained in this
document are presented only as guidance for Products use. Therefore, in case you use such information,
you are solely responsible for it and you must exercise you own independent verification and judgment in
the use of such information contained in this document. ROHM shall not be in any way responsible or
liable for damages, expenses or losses incurred by you or third parties arising from the use of such
information.
● Precaution for Electrostatic
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge.
Please take proper caution in your manufacturing process and storage so that voltage exceeding Products
maximum rating will not be applied to Products. Please take special care under dry condition (e.g.
Grounding of human body / equipment / solder iron, isolation from charged objects, setting of Ionizer,
friction prevention and temperature / humidity control).
● Precaution for Storage / Transportation
1) Product performance and soldered connections may deteriorate if the Products are stored in the places
where:
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2
[b] the temperature or humidity exceeds those recommended by ROHM
Temperature: 5C - 40C, Humidity: 40% - 60%RH
[c] the Products are exposed to direct sunshine or condensation
[d] the Products are exposed to high Electrostatic
2) Even under ROHM recommended storage condition, solderability of products out of recommended
storage time period may be degraded.
It is strongly recommended to confirm solderability before using Products of which storage time is
exceeding the recommended storage time period.
・Recommended storage condition: Temperature: 5C - 40C, Humidity: 40% - 60%RH
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.
4) Use Products within the specified time after opening a humidity barrier bag. Baking is required before
using Products of which storage time is exceeding the recommended storage time period.
･Maximum time : 72 hours, Temperature: 5C - 40C, Humidity: 40% - 60%RH
･Baking condition: Single type: 125C, 24 hours, up to once
