Product Description
The CSPEMI202A 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
microphone port on a cellular telephone or similar
device. Each high quality filter provides more than
35dB attenuation in the 800-2700 MHz range. These
pi-style filters support bidirectional filtering, controlling
EMI both to and from a microphone element. They also
support bipolar signals, enabling audio signals to pass
through without distortion.
In addition, the CSPEMI202A provides a very high
level of protection for sensitive electronic components
that may be subjected to electrostatic discharge (ESD).
The diodes safely dissipate ESD strikes of ±8kV, 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 ±15kV.
The CSPEMI202A 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 CSPEMI202A is available in a
space-saving, low-profile Chip Scale Package with
RoHS compliant lead-free finishing.
