Product Description
The CM1409 is a family of pi-style EMI filter arrays with
ESD protection, which integrates six and eight filters
(C-R-C) in small form factor TDFN 0.50mm pitch pack-
ages. The CM1409 has component values of 15pF-
100Ω-15pF per channel. The CM1409 has a cut-off fre-
quency of 110MHz and can be used in applications
with data rates up to 44Mbps. The parts include 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 safely dissipate ESD strikes of
±15kV,
well 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.
These devices are particularly well-suited for portable
electronics (e.g. wireless handsets, PDAs, notebook
computers) because of their small package and easy-
to-use pin assignments. In particular, the CM1409 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 CM1409 is housed in space-saving, low-profile 12-
and 16-lead TDFN packages with a 0.50mm pitch and
is available with lead-free finishing.
