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 rangeDC to > 50 MHz
Recommended frequency range100 Hz to 10 MHz (typ.)
Common Mode Inductance≥ 75 mH @ 1 kHz
Input-Output Capacitance175 - 205 pF @ 1 MHz
Signal connector typeBNC
