Product Description
The CM1400-03 is a six channel low-pass filter array
that reduces EMI/RFI emissions while at the same time
providing ESD protection. It is used on data ports on
mobile devices. To reduce EMI/RFI emissions, the
CM1400-03 integrates a pi-style filter (C-R-C) for each
of the 6 channels. Each high quality filter provides
greater than 30dB attenuation in the 800-2700 MHz
range relative to the pass band attenuation. These pi-
style filters also support bidirectional filtering, control-
ling EMI both to and from a data port connector.
In addition, the CM1400-03 provides a very high level
of protection for sensitive electronic components that
may be subjected to electrostatic discharge (ESD).
The input pins are designed and characterized to
safely dissipate ESD strikes of ±15kV, exceeding 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 ±30kV.
The CM1400-03 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package footprint and
low weight.
The CM1400-03 incorporates OptiGuard™ coating
which results in improved reliability at assembly. The
CM1400-03 is available in a space-saving, low-profile
chip scale package with optional lead-free finishing.
