Resistor Thin Film Precision
This specific product line is not for new designs.
Johanson’s Precision Thin Film Resistors (RNP Series) are designed for applications where close accuracy and exceptional stability are the critical parameters. The Precision Thin Film series are available in a wide range of industry standard case sizes including 0402, 0603, 0805, 1206, 2010 and 2512, with resistance values ranging from 1Ω to 3MΩ, and tight tolerances to ± 0.01%. With very low tolerances to ± 0.01% and low temperature coefficients to ± 5ppm/°C, the RNP series is an excellent solution for industrial applications.
