4- and 8-Channel EMI Filter Arrays with ESD Protection

An EMI filter array with ESD protection, which integrates either four or eight pi filters (C-R-C). The CM1407 has component values of 7.5pF-200Ω-7.5pF (fC = 210MHz). The 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 ±15 kV 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 ±30 kV.
