The CM1400-03 is a six channel low-pass filter array that reduces EMI/RFI emissions while at the same time providing ESD protection. It is used on data ports on mobile devices. To reduce EMI/RFI emissions, the CM1400-03 integrates a pi-style filter for each of the 6 channels. Each high quality filter provides greater than 30 dB attenuation in the 800-2700 MHz range relative to the pass band attenuation. These pi-style filters also support bidirectional filtering, controlling EMI both to and from a data port connector.
