Ultra Precision Resistor Networks

Serial Ultra Precision Resistor Networks

UPRNS

Token China UPRNS precision network series is serial dip type and assembled by EE 1/10 or RE 1/10 series, to form a stable, ultra precision, and low temperature coefficient network resistors. The UPRNS networks are relatively consistent with tolerance of nominal resistance and temperature coefficient.


Detailed precision UPRNS networks, both mechanical and electrical, please contact our sales representative for more information.
