Product Description
The CSPEMI307A is a multichannel EMI/ESD array offering a
combination of four lowïpass filter + ESD channels to reduce
EMI/RFI emissions on a data port and four dedicated ESDïonly
channels intended specifically for ESD protection on a USB port.
Each EMI/RFI channel integrates a high quality piïstyle filter
(CïRïC) which provides greater than 30 dB attenuation in the
800ï2700 MHz range. These piïstyle filters support bidirectional
filtering, controlling EMI both to and from a data port connector.
The CSPEMI307A provides a highïlevel 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 61000ï4ï2 international
standard. Using the MILïSTDï883 (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 spaceïsaving, lowïprofile Chip Scale
Package with leadïfree finishing.
Features Four Channels of Combined EMI/RFI Filtering + ESD Protection Four Additional Channels of ESDïOnly Protection EMI/ESD Channels Provide Greater than 32 dB Attenuation at GHz ±15 kV ESD Protection on all Channels
(IEC 61000ï4ï2 Level 4, Contact Discharge) ±30 kV ESD Protection on all Channels (HBM) Chip Scale Package Features Extremely Low Lead Inductance for
Optimum Filter and ESD Performance 15ïBump, 2.960 mm x 1.330 mm Footprint Chip Scale Package
(CSP) These Devices are PbïFree and are RoHS Compliant
Applications EMI Filtering and ESD Protection for both Data and I/O Ports Outer 4 Channels Provide ESD Protection for USB Lines and
other I/O Port Applications Wireless Handsets Handheld PCs / PDAs MP3 Players
