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
• EN140100
• 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 Ω 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
