UPRND Networks High Precision
Sharpen The Edge of Application Accuracy
Preview
The Precision Resistor Network technology provides a significant reduction of the resistive component’s
sensitivity to ambient temperature variations (TCR).
Designers can now guarantee a high degree of stability and accuracy in fixed-resistor applications using solutions
based on Token’s revolutionary Network technology. This technology allows customer orientated products,
designed to satisfy challenging and specific technical requirements.
Precision Network Resistors UPRND Series meets Lead (Pb)-free and RoHS compliant. Known for providing
design engineers with a comprehensive range of industrial-qualified resistive devices, Token Electronics has
further expanded its precision product capabilities in Serial UPRNS and Parellel UPRND Series.
Providing design engineers with an economical power resistor with high quality performance, Token Electronics
offers low cost industrial grade resistor networks, Parellel UPRND and Serial UPRNS Networks.
Token’s UPRND/UPRNS Series are assembled by EE/RE 1/10 series to form a stable, high precision resistor
networks. Characteristic of UPRND Series meet extreme low temperature coefficient.
Parellel UPRND Series equate IRC, EBG Precision Devices with fast delivery and more competitive price. For
non-standard technical requirements and special applications, please contact us.
