Product Description

The CSPEMI307A is a multichannel EMI/ESD array

offering a combination of four low-pass filter + ESD

channels to reduce EMI/RFI emissions on a data port

and four dedicated ESD-only channels intended

specifically for ESD protection on a USB port. Each

EMI/RFI channel integrates a high quality pi-style

filter (C-R-C) which provides greater than 30dB

attenuation in the 800-2700 MHz range. These pi-

style filters support bidirectional filtering, controlling

EMI both to and from a data port connector.

The CSPEMI307A provides a high-level of ESD

protection

on

all

eight

channels

for

sensitive

electronic components that may be subjected to

electrostatic discharge (ESD).

The input pins are

designed and characterized to safely dissipate ESD

strikes

of

±15kV,

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

device provides protection for contact discharges to

greater than ±30kV.

The CSPEMI307A is particularly well suited for

portable electronics (e.g., cellular telephones, PDAs,

notebook computers) because of its small package

footprint and low weight. The CSPEMI307A is

available in a space-saving, low-profile Chip Scale

Package with optional lead-free finishing.
