Product Description
California Micro Devices CM1407 is an EMI filter
array with ESD protection, which integrates either
four or eight pi filters (C-R-C). The CM1407 has
component values of 7.5pF-200W-7.5pF (f_C =
210MHz). The 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 CM1407 is
ideal for EMI filtering and protecting data lines from
ESD in wireless handsets.
The CM1407 is available in space-saving, low-profile,
8 and 16-lead TDFN packages. It is fabricated with
California Micro Devices' Centurion™ process and
available with optional lead-free finishing.
