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
