Product Description
The CSPEMI200A is a quad low-pass filter array inte-
grating four pi-style filters (C-R-C) that reduce EMI/RFI
emissions while at the same time providing ESD pro-
tection. This device is custom-designed to interface
with the headset port on a cellular telephone, and con-
tains 3 different filter values. Each high quality filter
provides more than 20dB attenuation in the 800-2700
MHz range. These pi-style filters support bidirectional
filtering, controlling EMI both to and from the micro-
phone and speaker elements. They also support bipo-
lar signals, enabling audio signals to pass through
without distortion.
In addition, the CSPEMI200A provides a very high
level of protection for sensitive electronic components
that may be subject to electrostatic discharge (ESD).
The CSPEMI200A 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 CSPEMI200A 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 CSPEMI200A is available in a
space-saving, low-profile Chip Scale Package with
optional lead-free finishing.
