Product Description
The CM1636 is an EMI filter array with ESD protection, which integrates either four, six or eight pi filters (C-R-C). Each CM1636 filter has component values of 15pF-200W-15pF. These parts include ESD protection diodes on every pin, providing a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±15kV contact discharge, twice the specification requirement of the IEC 61000-4-2, Level 4 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at 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 30dB of attenuation from 800MHz to 3GHz
• UDFN package with 0.40mm lead pitch:
    • 4-ch. = 8-lead UDFN
    • 6-ch. = 12-lead UDFN
