The CSE series coaxial current shunts are high-energy bolt-type ultrafast shunts for high-current pulse measurement on SiC and GaN power stages. Their coaxial resistor design gives bandwidths up to 1.5 GHz with a flat response and withstands transient pulse energy up to 20 J.

The shunt is clamped between two circuit boards with two sets of nuts and connects to the oscilloscope through a BNC output (50 Ω input impedance).
