6-Channel EMI Filter Array with ESD Protection

CM1440
6-Channel EMI Filter Array
with ESD Protection
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 (30 pF − 100 W − 30 pF) which provides greater
than 30 dB of attenuation in the 800 MHz to 2.7 GHz 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).
The ESD protection diodes connected to the filter ports safely
dissipate ESD strikes of ±30 kV, 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 ±30 kV.
This device is particularly well−suited for portable electronics (e.g.
wireless handsets, PDAs, notebook computers) 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 OptiGuardt which results in improved
reliability at assembly. The CM1440 is available in a space saving, low
profile Chip Scale Package with RoHS−compliant lead−free finishing.
It is manufactured with a 0.40 mm pitch and 0.25 mm CSP solder ball
to provide up to 28% board space savings versus competing CSP
devices with 0.50 mm pitch and 0.30 mm CSP solder ball.
