The CSF series flat coaxial current shunts are surface-soldered ultrafast shunts with a very small PCB footprint, designed for high-density SiC and GaN designs where board space is tight. Only input and output pads need to be reserved on the PCB; the shunt body is soldered directly onto them.

Bandwidths reach 1 GHz with no high-frequency insertion loss, and the signal is taken out through an MMCX connector.
