CM1441
4-Channel EMI Filter Array w/ ESD + 4-channel ESD Array
Features
Product Description
•
The CM1441 is a multichannel EMI/ESD array consisting of four low-pass filter + ESD channels to reduce
EMI emissions on data ports and lines and four dedicated ESD-only channels. Each EMI filter channel integrates a high quality pi-style filter (30pF-100Ω-30pF)
which provides greater than 30dB of attenuation in the
800MHz to 2.7GHz frequency range. The parts include
avalanche-type 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). All ESD protection
diodes safely dissipate ESD strikes of ±30kV, 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 at
greater than ±30kV.

•
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
This device is particularly well suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package format and easyto-use pin assignments. In particular, the CM1441 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 CM1441 incorporates OptiGuard™ which results
in improved reliability at assembly. The CM1441 is
available in a space-saving, low-profile Chip Scale
Package with optional lead-free finishing. It is manufactured with a 0.40mm pitch and 0.25mm CSP solder
ball to provide up to 28% board space saving vs. competing CSP devices with 0.50mm pitch and 0.30mm
CSP solder ball.
