LCD and Camera EMI Filter
Array with ESD Protection
CM1431
Features
Product Description
•
The CM1431 is a family of pi-style EMI filter arrays
with ESD protection, which integrates four, six and
eight filters (C-R-C) in small form factor TDFN
0.40mm pitch packages. The CM1431 has
component values of 15pF-100Ω-15pF per channel.
The CM1431 has a cut-off frequency of 120MHz and
can be used in applications with data rates up to
48Mbps. The parts include ESD diodes on every pin,
which provide a very high level of protection for
sensitive electronic components that may be
subjected to electrostatic discharge (ESD). The ESD
protection diodes safely dissipate ESD strikes of
±15kV, well beyond the maximum requirement of the
IEC61000-4-2 international standard. Using the MILSTD-883 (Method 3015) specification for Human
Body Model (HBM) ESD, the pins are protected for
contact discharges at greater than ±30kV.

TDFN package with 0.40mm lead pitch:
• 4-ch. = 8-lead TDFN
• 6-ch. = 12-lead TDFN
• 8-ch. = 16-lead TDFN
Tiny TDFN package size:
• 8-lead: 1.7mm x 1.35mm
• 12-lead: 2.5mm x 1.35mm
• 16-lead: 3.3mm x 1.35mm
Increased robustness against vertical impacts

Applications
•
•
•
•
•
•
LCD and Camera data lines in mobile handsets
I/O port protection for mobile handsets, notebook
computers, PDAs etc.
EMI filtering for data ports in cell phones, PDAs
or notebook computers.
Wireless handsets
Handheld PCs/PDAs
LCD and camera modules
These devices are particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of their small package and easyto-use pin assignments. In particular, the CM1431 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 CM1431 is housed in space-saving, low-profile
8-, 12- and 16-lead TDFN packages with a 0.40mm
pitch and is available with lead-free finishing. This
smaller size TDFN package provides up to 42%
board space saving vs. the 0.50mm pitch TDFN
packages.
