A Diverse Line that Meets any EMI Demand

Laird Technologies’ compact ferrite parts provides EMI suppression on conductors such as PC board traces (tracks) and high speed input/output circuitry (including network and storage subsystems).  These are the industry's only true monolithic common mode chokes.

Common mode chokes filter common mode EMI currents without causing signal degradation and without derating under high currents.  These components are applied to pairs of conductors – supply and return.  Common mode chokes are the ideal components for EMI filtering of power and signal lines.  These components withstand high DC currents without degradation of filtering performance that can occur with differential mode filters like small chip beads.  Stable common mode chokes allow most signals to pass unaffected, yet filter the noise (EMI) from these circuits.

Modern systems are frequently an interconnection of functional blocks and connections made by cables or wiring harnesses.  These interconnections often present the opportunity for common mode current loops between devices that can lead to EMI regulatory failure.  The addition of a common mode choke before the connector filters these common mode currents while allowing the desired signals to pass unaffected.  The result is effective communication between devices, reliable product and system operation and product EMI regulatory compliance.

Laird Technologies offers a very diverse common mode choke product line that meets the demand of any applications by providing the very best solution.
