Current compensated EMI noise suppression chokes for data and signal line filtering

We offer a comprehensive range of common mode noise suppression chokes designed for interfacing and reduction of electromagnetic interference (EMI). These chokes provide both differential and common mode noise attenuation while allowing the signal to pass through virtually undistorted.
The chokes are available in sizes ranging from standard to ultra miniature in both DIL and SMD styles and offer compatibility with all common footprints.
The quick reference chart shown below provides a quick overview of choices available from the broad selection being offered by us.		   Common Mode Filter Chokes
