Product Description
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.
