FIXED THICK FILM CHIP RESISTORS Series 1/14 SPECIFICATION PRODUCTS: FIXED THICK FILM CHIP RESISTORS TYPE: MCR01 MRT SERIES ROHM CO., LTD RESISTOR DIV FIXED THICK FILM CHIP RESISTORS Series 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 Cl , H S, NH , SO , and NO 2 2 3 2 2 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.
