SDN-XX Wideband Current Shunt

Brand: T&M Research
Origin: United States

SDN-XX Wideband Current Shunt

A wideband current shunt that converts measured current into a voltage signal.

Key specification options

Resistance (ohms): .001 / .0025 / .005 and more
Bandwidth (MHz): 12 / 400 / 1200 and more
Rise time (ns): 30 / 1 / 0.30 and more
Emax, joules: 12 / 28 / 3 and more

Product design

The SDN family includes several terminating configurations for compact coaxial measurement arrangements. Confirm the required construction and connections first, then compare models within that configuration rather than choosing by similar appearance.

Measurement and application

A shunt converts current into a voltage signal for measurement equipment. Selection involves its position in the current path as well as the arrangement of the voltage sensing connections.

Selection and connections

Consider whether the task involves continuous operation or pulse testing, then confirm mounting, connection space and instrument interface. Sensing connections, thermal conditions and circuit layout should follow the instructions for the chosen model.
