●Product Description
●The CM1431 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six and eight filters (C-R-C) in small form factor TDFN 0.40mm pitch packages. The CM1431 has component values of 15pF-100Ω-15pF per channel. The CM1431 has a cut-off frequency of 120MHz and can be used in applications with data rates up to 48Mbps. The parts include 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
●• Four, six and eight channels of EMI filtering with integrated ESD protection
