EMI Filter with ESD Protection

The CSPEMI400 is an EMI filter array with ESD protection, which integrates three pi filters (C-R-C) and two additional channels of ESD protection. The CSPEMI400 has component values of 20pF-47W- 20pF, and 20pF-100 Ohm-20pF. The parts include avalanche-type 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). The ESD diodes connected to the filter ports safely dissipate ESD ±strikes of 10kV, exceeding the maximum requirement of the IEC 61000-4-2 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 ±25kV.
