Product Description
The CM1406 is an EMI filter array with ESD
protection, which integrates either four or eight pi
filters (C-R-C). Each CM1406 filter has component
values of 15pF-200W-15pF. These parts include ESD
protection diodes on every pin, providing a very high
level of protection for sensitive electronic components
that may be subjected to electrostatic discharge
(ESD). The ESD diodes connected to the filter ports
safely dissipate ESD strikes of •15kV contact
discharge, twice the specification requirement of the
IEC 61000-4-2, Level 4 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.
This device is particularly well suited for portable
electronics (e.g. mobile handsets, PDAs, notebook
computers) because of its small package and easy-
to-use pin assignments. In particular, the CM1406 is
ideal for EMI filtering and protecting data lines from
ESD in wireless handsets.
The CM1406 is available in space-saving, low-profile,
8-lead and 16-lead TDFN packages. It is fabricated
with Centurion™ process and available with lead-free
finishing.
