Product Description
The CM1410 is a quad low-pass filter array
integrating four pi-style filters (C-R-C) that reduce
EMI/RFI emissions 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 three 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 microphone and speaker
elements. They also support bipolar signals, 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
international 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 single 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
RoHS-compliant, Chip Scale Package.
