Product Description
The CSPEMI201A is a dual low-pass filter array inte-
grating two pi-style filters (C-R-C) that reduce EMI/RFI
emissions while at the same time providing ESD pro-
tection. This part is custom-designed to interface with a
speaker port on a cellular telephone or similar device.
Each high quality filter provides more than 35dB atten-
uation in the 800-2700 MHz range. These pi-style fil-
ters support bidirectional filtering, controlling EMI both
to and from a speaker element. They also support
bipolar signals with a cutoff frequency of 31MHz,
enabling audio signals to pass through without distor-
tion.
In addition, the CSPEMI201A provides a very high
level of protection for sensitive electronic components
that may be subjected to electrostatic discharge (ESD).
The CSPEMI201A can safely dissipate ESD strikes of

The CSPEMI201A is particularly well-suited for porta-
ble electronics (e.g., cellular telephones, PDAs, note-
book computers) because of its small package and low
weight. The CSPEMI201A is available in a space-sav-
ing, low-profile Chip Scale Package with RoHS compli-
ant lead-free finishing.
