B-LCM is a low frequency common mode choke that can be used to reduce ground-loop currents in a test setup.
 
Typical Applications:
Reduce ground-loop error in Shunt-Thru measurements
Reduce/suppress common-mode signals
Quasi-isolate an input channel for high frequencies
 
Key Features:
Metal housing with BNC connectors
High inductance for low-frequency measurements
Low insertion loss and return loss
High common mode rejection of > 40dB @ 1Hz (typ.) and > 60dB @ 1kHz (typ.)
CE marking (RoHs)
 
Some Technical Data:
Usable frequency range – DC to > 50 MHz
Recommended frequency range – 100 Hz to 10 MHz (typ.)
Common Mode Inductance – >-75 mH @ 1 kHz
Sprung hook
Input-Output Capacitance – 175 – 205 pF @ 1 MHz
Signal connector type BNC
