RCME
Vishay Sfernice
Molded Metal Film Resistors Low Temperature Coefficient, High Precision
FEATURES
· 0.125W to 0.25W at 85°C · Very Low temperature coefficient: ± 5 and ± 10ppm/°C · Very tight tolerances: up to ± 0.1% T h e 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. L a s e r 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 >107M · Climatic category 65°C/+ 155°C/56 days · High frequency performance
