Product Description
The CM1461 is a family of pi-style EMI filter arrays with ESD protection, which integrates four, six and eight filters (C-L-C) in small form factor TDFN 0.50mm pitch packages. Each EMI filter channel of the CM1461 is implemented as a 3-pole L-C filter where the component values are 10pF-20nH-10pF. The CM1461's roll-off frequency at -6dB attenuation is 400MHz and can be used in applications where the data rates are as high as 140Mbps while providing greater than 30dB over the 800MHz to 2.7GHz frequency range.

FEATUREs
• Four, six, and eight channels of EMI filtering with integrated ESD protection
• Pi-style EMI filters in a capacitor-inductor capacitor (C-L-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 20dB attenuation (typical) at 1GHz
• TDFN lead-free package with 0.50mm lead pitch:
   • 4-ch. = 8-lead TDFN
   • 6-ch. = 12-lead TDFN
   • 8-ch. = 16-lead TDFN
• Tiny TDFN package size:
   • 8-lead: 2.00mm 2.00mm
   • 12-lead: 3.00mm x 1.35mm
   •1 6-lead: 4.00mm x 1.60mm
• Increased robustness against vertical impacts during manufacturing process
• Lead-free RoHS compliant finishing
