Ultra-Fast Current Shunt UFCS
■ Ultra-low <150 pH Insertion Inductance
■ Various sizes available: 1 mΩ, 5 mΩ, 11 mΩ, 24 mΩ, 52 mΩ
■ For WBG switching loss and pulse current measurements
The Ultra-Fast Current Shunts (UFCS) represent a paradigm shift in the realm of current measurement technology, setting new standards in terms of technological sophistication. >1 GHz bandwidth and ultra low insertion inductance of <150 pH enable the precise analysis of fast rise time signals with exceptional signal fidelity, making PMK’s shunts with non-inductive frequency response ideal for challenging measurements like WBG (wide-bandgap) switching loss or pulse current analysis.
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.
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 FireFly®. For general purpose measurements the UFCS can also be connected directly to an 50 Ω input measuring instrument.
