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.

Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin. For example, if ESD is applied to Pin A1,
then clamping voltage is measured at Pin C1.
