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
8kV, the maximum requirement of the IEC 61000-4-2
international standard.
Using the
(Method 3015) specification for Human Body Model
(HBM) ESD, the device provides protection for contact
discharges to greater than 15kV.
MIL-STD-883
The CSPEMI201A is particularly well suited for porta-
ble electronics (e.g., cellular telephones, PDAs, note-
book computers) because of its small package format
and low weight. The CSPEMI201A is available in a
space-saving, low-profile Chip Scale Package with
optional lead-free finishing.
