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 specif-

ically 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 pro-

tection on all eight channels for sensitive electronic

components that may be subjected to electrostatic dis-

charge (ESD). The input pins are designed and char-

acterized 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 porta-

ble electronics (e.g., cellular telephones, PDAs, note-

book computers) because of its small package

footprint and low weight. The CSPEMI307A is avail-

able in a space-saving, low-profile Chip Scale Package

with optional lead-free finishing.
