B-LCM Low Frequency Common Mode Choke

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
