CSPEMI307A
4-Channel ESD/EMI Filter
Array Plus 4-Channel ESD
Array for USB
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 30 dB 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 ±15 kV, 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 ±30 kV.
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 lead−free finishing.
