Product Description
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.
