DDaattaasshheeeett Notice Precaution on using ROHM Products 1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment, OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment inc luding car accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bordily injury or serious damage to property (“Specific 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 responsibleo 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. f (Note1) Medical Equipment Classification of the Specific Applications JAPAN USA EU CHINA d CLASSⅢ CLASSⅡb CLASSⅢ CLASSⅢ CLASSⅣ CLASSⅢ e 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 implemdent, 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 meassures: n [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 n e 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. Accordinggly, ROHM shall not be in any way m 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 i extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of s product performance, reliability, etc, prior to usme, 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 Prodeucts are exposed to direct sunlight or dust [c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2 o D [d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves [e] Use of our Products inc proximity to heat-producing components, plastic cords, or other flammable items [f] Sealing or coating our Products with resin o r other coating materials [g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of w flux is recommeended); or Washing our Products by using water or water-soluble cleaning agents for cleaning residue after soldering [h] Use of thRe Products in places subject to dew condensation e 4. The Products are not subject to radiation-proof design. N 5. Pleaset verify and confirm characteristics of the final or mounted products in using the Products. 6. Ino 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 N product performance and reliability. 7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual ambient temperature. 8. Confirm that operation temperature is within the specified range described in the product specification. 9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in this document. 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 on a surface-mount products, the flow soldering method must be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products, please consult with the ROHM representative in advance. For details, please refer to ROHM Mounting specification Notice-PGA-E Rev.001 © 2015 ROHM Co., Ltd. All rights reserved.

DDaattaasshheeeett 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 your 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 any damages, expenses or losses incurred by you or third parties arising from the use of such information. r o Precaution for Electrostatic This Product is electrostatic sensitive product, which may be damaged due to electrostatic dischafrge. Please take proper caution in your manufacturing process and storage so that voltage exceeding the 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 / humididty control). Precaution for Storage / Transportation e 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 ROHdM [c] the Products are exposed to direct sunshine or condensation [d] the Products are exposed to high Electrostatic s n 2. Even under ROHM recommended storage condition, solderability of products out of rencommended storage time period may be degraded. It is strongly recommended to confirm soldeerability before using Products of which storage time is exceeding the recommended storage time period. m g 3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. i s 4. Use Products within the specified time after opmening a humidity barrier bag. Baking is required before using Products of which storage time is exceeding the recommended storage time period. e Precaution for Product Label o QR code printed on ROHM Products label is for ROHM’s internDal use only. Precaution for Disposition c When disposing Products please dispose them properly using an authorized industry waste company. w e Precaution for Foreign Exchange and Foreign Trade act Since concerned goods might be fallen under listed items of export control prescribed by Foreign exchange and Foreign trade act, please consRult with ROHM in case of export. e Precaution Regarding Intellectual Property Rights 1.
