EMI Filter with ESD Protection

The CSPEMI204 is an L−R−C EMI filter array with ESD protection that integrates two Pi−filters (C−L−R−C) to suppress EMI/RFI Noise.CSPEMI204 includes ESD protection diodes on all input/output pins, and provides a very high level of protection for sensitive electronic components against possible electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±30 kV, which is beyond the maximum requirement of the IEC61000−4−2 international standard.
