Product Description

The CM1440 is a six channel low-pass EMI filter array with ESD protection that reduces EMI/RFI emissions while providing robust protection from ESD strikes. Each EMI filter channel integrates a high quality pi-style filter (30pF-100Ω-30pF) which provides greater than 30dB of attenuation in the 800MHz to 2.7GHz frequency range. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).

Features

• Six channels of EMI filtering for data ports
