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.
