Product Description
The CM1410 is a quad low-pass filter array integrating
four 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 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 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 CM1410 provides a very high level of
protection for sensitive electronic components that may
be subject to electrostatic discharge (ESD). The
CM1410 can 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 CM1410 also includes a sin-
gle channel of ESD-only protection.
The CM1410 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package format and
low weight.
The CM1410 incorporates
Optiguard
coating which
results in improved reliability at assembly.The CM1410
is available in a space-saving, low-profile Chip Scale
Package with optional lead-free finishing.
