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 where the data rates are as high as 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). The ESD protection diodes safely dissipate ESD strikes of ±15kV, well beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV.

These devices are particularly well-suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of their small package and easy-to-use pin assignments. In particular, the CM1431 is ideal for EMI filtering and protecting data and control lines for the I/O data ports, LCD display and camera interface in mobile handsets.

The CM1431 is housed in space-saving, low-profile 8, 12 and 16-lead TDFN packages where the pitch is 0.40mm and is available with lead-free finishing. This new small TDFN package provides up to 42% board space saving vs. the 0.50mm pitch TDFN packages.

Note: Some of the devices listed here have suggested replacements available. Please see additional information at the end of this page.
