PRODUCTS TYPE FIXED THICK FILM CHIP RESISTORS ＭＣＲ１８ Series SPECIFICATION PRODUCTS: FIXED THICK FILM CHIP RESISTORS TYPE: MCR18 ERT SERIES ROHM CO., LTD．RESISTOR DIV． DESIGN CHECK APPROVAL DATE: 10/Nov/2011 REV. ００１Ｅ TSZ22111･04･002 SPECIFICATION No.：ＭＣＲ１８Ｒ－ＩＡ PAGE 1/14 PRODUCTS TYPE FIXED THICK FILM CHIP RESISTORS ＭＣＲ１８ Series PAGE 2/14 < Specifications (Precautions and Prohibitions) > ● 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 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 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 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) Verification and confirmation of performance characteristics of product, after on-board mounting, is advised. 5)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. 6) De-rate Power Dissipation(Pd)depending on Ambient temperature(Ta). 7) Confirm that operation temperature is within the specified range described in product specification. 8) Product may be damaged when the impact, such as downfall is given. 9) Failure induced under deviant condition from what defined in the product specification can be not be Guaranteed. 10)When product safety related problems arises, please immediately inform to ROHM, and consider technical counter measure.

There may be a case that the overcoat and /or the body can be chipped. 5) Soldering tip shall not touch the product when install product manually. ● 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. ● Precaution for Electrostatic This product is Electrostatic sensitive product, which may be damaged due to Electrostatic discharge. Please take proper caution during manufacturing and string so that voltage exceeding Product maximum rating won’t 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 strage/Transportation 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 Cl2, H2S, NH3, SO2, and NO2 [b] Where the temperature or humidity exceeds those recommended by the Company Temperature:5―40℃, Humidity 30―80% (Put condition for individual product) [c] Storage in direct sunshine or condensation [d] Storage in high Electrostatic 2) Even under ROHM recommended storage condition, solderability of products over 1 year old (Put condition for each product)may be degraded. It is strongly recommended storage time period. ･Recommended storage condition：Temperature 5―40℃, Humidity 30―80%(Put condition for individual product) 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. ● Precautions for Foreign exchange control regulation ROHM 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.
