Parallel Precision Resistor Network Voltage Divider (UPRND)

Direct's (UPRND) high precision voltage divider networks sharpen the edge of application accuracy.

The Precision Thin-Film 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 Direct'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, Direct Electronics has further expanded its precision product capabilities in Serial UPRNS and Parallel UPRND Series.

Providing design engineers with an economical power resistor with high quality performance, Direct Electronics offers low cost industrial grade Parallel UPRND and Serial UPRNS Networks.

Direct's UPRND/UPRNS Series are assembled by EE/RE 1/10 series to form a stable, high precision thin-film networks. Characteristic of UPRND Series meet extreme low temperature coefficient.

Parallel 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.
