Product Description
California Micro Devices's 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-200Ω-7.5pF. 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 dis-
sipate 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 dis-
charges at greater than ±30kV.
This device is particularly well-suited for portable elec-
tronics (e.g. mobile handsets, PDAs, notebook com-
puters) 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.
