Steward's ultra high current common mode chokes provide small form factor, high performance and economical power filtering for common mode noise in applications up to 55 amps. They provide EMI suppression for groups of conductors like power traces and high speed data lines.

Steward

Ultra High Current Common Mode Chokes

Steward's monolithic surface mount common mode chokes are designed for power and data line EMI filtering where high current, small size or high frequency performance is required. Steward's advanced high frequency material is used to push performance out into the GHz range. This high current choke has a self-resonant frequency at 6 GHz in a low profile, small package size. Effective in filtering power lines or high speed data lines (including network & storage subsystems).

SMD - EMI Components

In Ferroxcube’s SMD Common Mode Chokes, 2 or 4 conductors within a single soft-ferrite block are connected along their lengths by an air gap.

Common mode signals - interference signals passing in the same direction along the input and output channels of a device (e.g. and IC) - reinforce the magnetic flux around both conductors, and are therefore attenuated. In contrast, the wanted signal passing along the input and output channels cancel the flux around the conductors and therefore passes unattenuated.
