format product datasheet

The CM1426 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six and eight filters (C-R-C) in a Chip Scale Package with 0.50mm pad pitch. The CM1426 has component values of 8.5pF-100Ω-8.5pF per channel. The CM1426 has a cut-off frequency of 230MHz and can be used in applications where the data rates are as high as 92Mbps. The parts include avalanche-type ESD diodes on every pin that provide a very high level of protection for sensitive electronic components against possible ESD strikes. The ESD protection diodes safely dissipate ESD strikes of ±8kV, 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 ±15kV.

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 CM1426 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 CM1426 incorporates Optiguard™ which results in improved reliability at assembly. The CM1426 is available in a space-saving, low-profile Chip Scale Package.

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