CM1441

4-Channel EMI Filter Array w/ ESD + 4-channel ESD Array

Features

Product Description

•

Four channels of EMI filtering with integrated ESD

protection

The CM1441 is a multichannel EMI/ESD array consist-

ing of four low-pass filter + ESD channels to reduce

EMI emissions on data ports and lines and four dedi-

cated ESD-only channels. Each EMI filter channel inte-

grates 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 pro-

vide a very high level of protection for sensitive elec-

tronic 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 inter-

national 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.

Four channels of ESD-only protection

0.4mm pitch, 15-bump, 2.360mm X 1.053mm foot-

print Chip Scale Package (CSP)

Pi-style EMI filters in a capacitor-resistor-capacitor

(C-R-C) network

30kV ESD protection on each channel

(IEC 61000-4-2 Level 4, contact discharge)

30kV ESD protection on each channel (HBM)

Greater than 35dB attenuation (typical) at 1 GHz

Chip Scale Package features extremely low

lead inductance for optimum filter and ESD

performance

•

OptiGuard™ coated for improved reliability at

assembly

Lead-free version available

This device is particularly well suited for portable elec-

tronics (e.g. wireless handsets, PDAs, notebook com-

puters) because of its small package format and easy-

to-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.

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.

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 manu-

factured with a 0.40mm pitch and 0.25mm CSP solder

ball to provide up to 28% board space saving vs. com-

peting CSP devices with 0.50mm pitch and 0.30mm

CSP solder ball.
