Product Description
The CSPEMI205 is a low-pass filter array integrating
three pi-style filters (C-R-C) that reduce EMI/RFI emis-
sions while at the same time providing ESD protection.
This device is custom-designed to interface with the
headset port on a cellular telephone, and contains two
different filter values. Each high quality filter provides
more than 30dB attenuation in the 800-2700 MHz
range. These pi-style filters support bidirectional filter-
ing, controlling EMI both to and from the microphone
and speaker elements. They also support bipolar sig-
nals, enabling audio signals to pass through without
distortion.
In addition, the CSPEMI205 provides a very high level
of protection for sensitive electronic components that
may be subject to electrostatic discharge (ESD). The
input pins are designed and characterized to safely dis-
sipate ESD strikes of
+
8kV, the maximum requirement
of the IEC 61000-4-2 international standard. Using the
MIL-STD-883 (Method 3015) specification for Human
Body Model (HBM) ESD, the device provides protec-
tion for contact discharges to greater than
+
15kV.
The CSPEMI205 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package format and
low weight. The CSPEMI205 is available in a space-
saving, low-profile Chip Scale Package with optional
lead-free finishing.
