1 Vishay Sfernice Molded Metal Film High Stability (< 0.25 % after 1000 h) FEATURES 0.1 W to 2 W at 125 C EN CECC High climatic performance 65 C/+ 175 C/56 days High long term stability drift < 0.25 % after 1000 h The performance of the resistors exceed the requirements of NF C standards. They are particularly relevant to the more stringent military and industrial applications especially when high ambient temperatures such as C are to be encountered. The resistors are qualified and released to the NF C UTE standard styles 56C, 60E and C, 65E and C, 70E and C. Tight temperature coefficient to ± 15 ppm/ C Temperature coefficient tracking 5 ppm/ C Wide ohmic range from to 5 MΩ Tight tolerances up to ± 0.1 % Matching tolerance to 0.05 % Termination: Pure matte tin Compliant to RoHS directive 2002/95/EC DIMENSIONS in millimeters 25 min. 25 min.

It progressively increases as a function of the ohmic value and can reach 0.2 µv/v for the highest values of models 02 and 05 (0.1 µv/v for R < 10 kω). 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 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. Document Number: For technical questions, contact: sfer@vishay.com Revision: 02Oct09 179
