Product Description
The CM1630 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 UDFN 0.40mm pitch packages. The CM1630 has component values of 8.5pF-100Ω-8.5pF per channel. The CM1630 has a cut-off frequency of 200MHz and can be used in applications with data rates up to 80Mbps. 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-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 25dB 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: 1.7mm x 1.35mm x 0.5mm
    • 12-lead: 2.5mm x 1.35mm x 0.5mm
    • 16-lead: 3.3mm x 1.35mm x 0.5mm
• Increased robustness against vertical impacts during manufacturing process
• Lead-free version available
