6 Channel EMI Filter Array with ESD Protection

Product Description

Features

•

Six channels of EMI filtering for data ports

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

(C-R-C) network

The CM1440 is a six channel low-pass EMI filter array

with ESD protection that reduces EMI/RFI emissions

while providing robust protection from ESD strikes.

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 fre-

quency 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). The

ESD protection diodes connected to the filter ports

safely dissipate ESD strikes of 30kV, beyond the

maximum requirement of the IEC61000-4-2 interna-

tional 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.

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

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

print Chip Scale Package (CSP)

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

Applications

•

This device is particularly well-suited for portable elec-

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

puters) because of its small package and easy-to-use

pin assignments. In particular, the CM1440 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.

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

The CM1440 incorporates OptiGuard™ which results

in improved reliability at assembly. The CM1440 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 savings versus

competing CSP devices with 0.50mm pitch and

0.30mm CSP solder ball.
