Vishay Sfernice
Molded Metal Film Resistors
Low Temperature Coefficient, High Precision
FEATURES
•
0.125 W to 0.25 W at 85 °C
•
Very low temperature coefficient: ± 5 ppm/°C
and ± 10 ppm/°C
The RCME range of metal film resistors represents a
significant technical advancement in resistive technology,
combining low temperature coefficients with high
environmental stabilities, and high frequency performance.
Laser beam trimming gives tolerance accuracies from 0.1 %
to 1 %.
The RCME range effectively bridges the gap that has
hitherto existed between the high precision, high stability foil
or wirewound technology and conventional film technology.
•
Very tight tolerances: Down to ± 0.1 %
•
Electrical insulation > 10
