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
Tight temperature coefficient to 15 ppm/C
The performance of the RCMT resistors exceed the
Temperature coefficient tracking 5 ppm/C
requirements of NF C 83-230 standards. They are
particularly relevant to the more stringent military and
Wide ohmic range from 1 to 5 M
industrial applications especially when high ambient
Tight tolerances up to 0.1 %
temperatures such as + 175 C are to be encountered.
Matching tolerance to 0.05 %
The RCMT resistors are qualified and released to the
Termination: Pure matte tin
NF C UTE 83-230 standard styles RS56C, RS60E and C,
Material categorization: for definitions of compliance
RS65E and C, RS70E and C.
