RCME 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 > 107 M * Climatic category - 65 C/+ 155 C /56 days * Excellent frequency performance * Termination = Pure matte tin * Compliant to RoHS directive 2002/95/EC DIMENSIONS in millimeters A 25 min. 25 min.
