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
• According to 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
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 manufactured according to the
NF C UTE 83-230 standard styles RS56C, RS60E and C,
RS65E and C, RS70E and 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

NOISE LEVEL
In a frequency decade, the average noise level is 0.1 μV/V
for models RCMT08, RCMT1, RCMT2, and RCMT4 in all
ohmic values. It progressively increases as a function of the
ohmic value and can reach 0.2 μV/V for the highest values of
models RCMT02 and RCMT05 (0.1 μV/V for R < 10 kΩ).
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.
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.
MARKING
Printed: Series, style, ohmic value (in

space, RCMT02 is referenced as MT02.
