EMI Filter with ESD
Protection
EMI7112
Product Description
The EMI7112 is an L−C EMI filter array with ESD protection that
integrates two Pi−filters (C−L−C) to suppress EMI/RFI Noise.
EMI7112 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
