Product Description
The CM1401-32CP is a multichannel array with four
low-pass filter + ESD channels and four ESD-only
channels. The CM1401-32CP reduces EMI/RFI emis-
sions on a data port and protects against ESD on a
USB port. Each EMI/RFI channel integrates a high
quality pi-style filter (C-R-C) that provides greater
than 30dB attenuation in the 800-2700 MHz range
relative to the pass band attenuation. These pi-style
filters are bidirectional, controlling EMI both to and
from a data port connector.
The CM1401-32CP provides a high-level of ESD pro-
tection on all eight channels for sensitive electronic
components that may be subjected to electrostatic
discharge (ESD). The input pins 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 CM1401-32CP is particularly well suited for
portable electronics (e.g., cellular telephones, PDAs,
notebook computers) because of its small package
footprint and low weight.
The CM1401-32CP incorporates OptiGuard™ coating
for improved reliability at assembly and comes in a
space-saving, low-profile Chip Scale Package with
RoHS-compliant lead-free finishing.
