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 0.40mm pitch package. The CM1631 has component values of 15pF-100W-15pF per channel with a cut-off frequency of 120MHz, and can be used in applications with data rates up to 48Mbps. 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 ±15kV, 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 ±30kV.

Features

• Four, six and eight channels of EMI filtering with integrated ESD protection

• Pi-style EMI filters in a capacitor-resistorcapacitor (C-R-C) network

• ±15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)

• ±30kV ESD protection on each channel (HBM)

• Greater than 35dB attenuation (typical) at 1 GHz

• uDFN package with 0.40mm lead pitch:

• 4-ch. = 8-lead uDFN

• 6-ch. = 12-lead uDFN

• 8-ch. = 16-lead uDFN

• Tiny uDFN package size:

• 8-lead: 1.70mm x 1.35mm x 0.50mm

• 12-lead: 2.50mm x 1.35mm x 0.50mm

• 16-lead: 3.30mm x 1.35mm x 0.50mm

• Increased robustness against vertical impacts during manufacturing process

• Lead-free finishing, RoHS compliant
