EMI Filter >35dB Flat Style SMD T/R

The CM1631 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six, or eight filters (C-R-C) in a small form factor, UDFN 0.40 mm pitch package. The CM1631 has component values of 15 pF - 100 - 15 pF per channel with a cut-off frequency of 120 MHz, and can be used in applications with data rates up to 48 Mbps. The device includes ESD diodes on every pin, that provide a very high level of protection for sensitive electronic components against possible electrostatic discharge (ESD). The ESD protection diodes safely dissipate ESD strikes of ±15 kV, which is 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 greater than ±30 kV. 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 CM1631 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.
