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 are designed and characterized to
safely dissipate ESD strikes of 15kV, exceeding the
maximum requirement of the IEC 61000-4-2 interna-
tional 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 available in a
space-saving, low-profile Chip Scale Package with
optional lead-free finishing.
