The CM1401-03 is a multichannel array with four low-pass filter + ESD channels and four ESD-only channels. The CM1401-03 reduces EMI/RFI emissions on a data port and protects against ESD on a USB port. Each EMI/RFI channel integrates a high quality pi-style filter (C-R-C) that provides greater than 30 dB attenuation in the 800 to 2700 MHz range relative to the pass band attenuation. These pi-style filters are bidirectional, controlling EMI both to and from a data port connector.
