Product Description
The CM1401-03 is a multichannel array with four low-
pass filter + ESD channels and four ESD-only chan-
nels. They reduce EMI/RFI emissions on a data port
and protect against ESD on a USB port. Each EMI/RFI
channel integrates a high quality pi-style filter (C-R-C)
which provides greater than 30dB attenuation in the
800-2700 MHz range relative to the pass band attenu-
ation. These pi-style filters are bidirectional, controlling
EMI both to and from a data port connector.
The CM1401-03 provides a high-level of ESD protec-
tion on all eight channels for sensitive electronic com-
ponents 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 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 30kV.
The CM1401-03 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package footprint and
low weight.
The CM1401-03 incorporates Optiguard
TM
coating
which results in improved reliability at assembly and is
available in a space-saving, low-profile chip scale
package with optional lead-free finishing.
