LCD and Camera EMI Filter
Array with ESD Protection
CM1426
Features
Product Description
•
The CM1426 is a family of pi-style EMI filter arrays
with ESD protection, which integrates four, six and
eight filters (C-R-C) in a Chip Scale Package with
0.50mm pad pitch. The CM1426 has component
values of 8.5pF-100Ω-8.5pF per channel. The
CM1426 has a cut-off frequency of 230MHz and can
be used in applications where the data rates are as
high as 92Mbps. The parts include avalanche-type
ESD diodes on every pin that provide a very high
level of protection for sensitive electronic components
against possible ESD strikes. The ESD protection
diodes safely dissipate ESD strikes of ±8kV, well
beyond the maximum requirement of the IEC610004-2 international standard. Using the MIL-STD-883
(Method 3015) specification for Human Body Model
(HBM) ESD, the pins are protected for contact
discharges at greater than ±15kV.

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 CM1426 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 CM1426 incorporates Optiguard which results
in improved reliability at assembly. The CM1426 is
available in a space-saving, low-profile Chip Scale
Package.
