Ultra-Fast Current Shunt UFCS IWATSU ELECTRIC

Double Pulse Test for SiC and GaN

The UFCS models' compact form factor and high current carrying capacity ensure consistent and reliable performance. Whether measuring GaN switching losses or analyzing high-frequency transients, the solder-in shunts always guarantee highest accuracy.

■ Market-leading >1GHz Bandwidth
■ Ultra-low <200 pH Insertion Inductance
■ Various sizes available: 5mΩ, 11mΩ, 24mΩ, 52mΩ
■ For WBG switching loss and pulse current measurements


The UFCS are a result of technological advancement that has not been surpassed in the field of current measurement in modern power electronics. For measurements with highest CMRR requirements the UFCS can be connected to optically isolated voltage probes, like PMK’s FF-1500.
For general purpose measurements the UFCS can also be connected directly to an 50 Ω input measuring instrument. The first model releases of the UFCS shunt series are the 11 mΩ, 24 mΩ and 52 mΩ versions.
