Common mode EMI suppression inductor for electronics
LAIRD TECHNOLOGIES

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.
