Product Description

The CM1431 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six and eight filters (C-R-C) in small form factor TDFN 0.40mm pitch packages. The CM1431 has component values of 15pF-100Ω-15pF per channel. The CM1431 has a cut-off frequency of 120MHz and can be used in applications with data rates up to 48Mbps. The parts include 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).

Features

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

• Pi-style EMI filters in a capacitor-resistor capacitor (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

• TDFN package with 0.40mm lead pitch:

• 4-ch. = 8-lead TDFN

• 6-ch. = 12-lead TDFN

• 8-ch. = 16-lead TDFN

• Tiny TDFN package size:

• 8-lead: 1.7mm x 1.35mm

• 12-lead: 2.5mm x 1.35mm

• 16-lead: 3.3mm x 1.35mm

• Increased robustness against vertical impacts during manufacturing process

• Lead-free finishing
