Product Description
The CM1631 is a family of pi-style EMI filter arrays
with ESD protection, which integrates four, six, or
eight filters (C-R-C) in a small form factor, uDFN
0.40mm pitch package. The CM1631 has component
values of 15pF-100W-15pF per channel with a cut-off
frequency of 120MHz, and can be used in
applications with data rates up to 48Mbps. The
device includes ESD diodes on every pin, that
provide a very high level of protection for sensitive
electronic components against possible electrostatic
discharge (ESD). The ESD protection diodes safely
dissipate ESD strikes of ±15kV, which is well beyond
the maximum requirement of the IEC61000-4-2
international standard. Using the MIL-STD-883
(Method 3015) specification for Human Body Model
(HBM) ESD, the pins are protected for contact
discharges greater than ±30kV.
These devices are particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of their small package and easy-
to-use pin assignments. In particular, the CM1631 is
ideal for EMI filtering and protecting data and control
lines for the I/O data ports, LCD display and camera
interface in mobile handsets.
The CM1631 is housed in space-saving, ultra-low-
profile 8-, 12- and 16-lead uDFN packages with a
0.40mm pitch and is available with lead-free finishing.
This smaller size uDFN package provides up to 42%
board space saving vs. the 0.50mm pitch uDFN
packages.
