MF4200

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.
