Product Description
The CSPEMI306A is a six channel low-pass filter array
that reduces EMI/RFI emissions while at the same time
providing ESD protection. It is used on data ports on
mobile devices. To reduce EMI/RFI emissions, the
CSPEMI306A integrates a pi-style filter (C-R-C) for
each of the 6 channels. Each high quality filter provides
greater than 30dB attenuation in the 800-2700 MHz
range. These pi-style filters also support bidirectional
filtering, controlling EMI both to and from a data port
connector.
In addition, the CSPEMI306A provides a very high
level of protection for sensitive electronic components
that may be subjected to electrostatic discharge (ESD).
The input pins 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 CSPEMI306A 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 CSPEMI306A is avail-
able in a space-saving, low-profile Chip Scale Package
with optional lead-free finishing.
