Product Description
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-100
Ω
-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.
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.
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.
