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
• Very tight tolerances: down to ± 0.1 %
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.
• Electrical insulation > 10

M
• Climatic category - 65 °C/+ 155 °C /56 days
• Excellent frequency performance
• Termination = pure matte tin
• Material categorization: For definitions of compliance
