RCMT Vishay Sfernice Molded Metal Film High Stability (< 0.25 % after 1000 h) High Temperature (up to 175 C) Precision Resistors FEATURES * 0.1 W to 2 W at 125 C * EN 140-100 * CECC 40 101-044 * High climatic performance - 65 C/+ 175 C/56 days * High long term stability drift < 0.25 % after 1000 h The performance of the RCMT resistors exceed the requirements of NF C 83-230 standards. They are particularly relevant to the more stringent military and industrial applications especially when high ambient temperatures such as + 175 C are to be encountered. The RCMT resistors are qualified and released to the NF C UTE 83-230 standard styles RS56C, RS60E and C, RS65E and C, RS70E and C. * Tight temperature coefficient to 15 ppm/C * Temperature coefficient tracking 5 ppm/C * Wide ohmic range from 1 to 5 M * Tight tolerances up to 0.1 % * Matching tolerance to 0.05 % * Termination: Pure Matt Tin DIMENSIONS in millimeters 25 min.

It progressively increases as a function of the ohmic value and can reach 0.2 V/V for the highest values of models RCMT02 and RCMT05 (0.1 V/V for R < 10 k). SPECIAL APPLICATIONS Temperature coefficient tracking to 5 ppm. Tolerance matching to 0.05 %. Selection of positive or negative TCR in temperature range of - 20 C to + 125 C. For these applications and other requirements consult VISHAY SFERNICE. RECOMMENDATION The lower the ohmic value, the more important the influence of lead resistance is on measurements. The nominal resistance value is therefore measured at a distance of 5 mm from resistor body. www.vishay.com 39 For technical questions, contact: sfer@vishay.com Document Number: 52011 Revision: 23-Sep-08 RCMT Molded Metal Film High Stability (< 0.25 % after 1000 h) High Temperature (up to 175 C) Precision Resistors Vishay Sfernice MARKING Printed: series, style, NF style if applicable, ohmic value (in ), tolerance (in %), temperature coefficient, manufacturing date.
