EMI1051/D

EMI Filter with ESD

Protection

EMI1051

The EMI1051 is an R−C EMI filter array with bidirectional ESD

protection that integrates a Pi−filter (C−R−C) to suppress EMI/RFI

Noise. EMI1051 includes ESD protection diodes on the input and

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.

Features

• Small Form Factor

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

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

• Greater than 30 dB of Attenuation in the 600 MHz − 1.55 GHz

Range

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

Compliant

Applications

• Mobile Phones

• Tablets

• Laptops
