Product Description

The CM1442 is a family of pi-style EMI filter arrays with ESD protection, which integrates six and eight filters (C-R-C) in Chip Scale Package form factor with 0.40mm pitch. The CM1442 has component values of 15pF-100Ω-15pF per channel. The CM1442 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 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).
