Product Description
The CM1409 is a family of pi-style EMI filter arrays
with ESD protection, which integrates either six or
eight filters (C-R-C) in a small form factor, TDFN
0.50mm pitch package. The CM1409 has component
values of 15pF-100Ω-15pF per channel. The
CM1409 has a cut-off frequency 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 against electrostatic discharge
(ESD). The ESD protected diodes safely dissipate
ESD strikes of ±15kV, which even exceeds 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, RoHS-compliant, lead-free finishing.
