EMI Filter with ESD Protection

The CSPEMI306A 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 CSPEMI306A integrates a pi-style filter (C-R-C) for each of the 6 channels. Each high quality filter provides greater than 30dB attenuation in the 800-2700 MHz range. These pi-style filters also support bidirectional filtering, controlling EMI both to and from a data port connector.
