CSPEMI204

EMI Filter with ESD
Protection

Product Description

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.

Features

• Two Channels of EMI Filtering

• ±30 kV ESD Protection (IEC 61000−4−2, Contact Discharge)

• ±30 kV ESD Protection (IEC 61000−4−2, Air Discharge)

• Greater than 45 dB of Attenuation at 900 MHz

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS

Compliant
