MF4200 Series Precision Metal Film Resistor Networks RIEDON Compact Design for High Population Boards Very Low Noise and Inductance Resistances from 100W to 100KW Absolute Tolerances to ± 0.1% Tolerance Ratios to ± 0.05% Low Temperature Coefficient to ± 5ppm/°C Riedon's high precision, metal film networks use stable NiCR film deposited on a high purity ceramic substrate. The resistor elements are formed using photolithography, then micro trimmed to tolerance. Planar construction ensures very low noise and inductance, making these networks ideal for high frequency applications.
