Product Description
California Micro Devices's CM1406 is an EMI filter
array with ESD protection, which integrates 4 pi filters
(C-R-C). The CM1406 has component values of 15pF-
200
-15pF. The parts include ESD protection diodes
on every pin, which provide a very high level of protec-
tion for sensitive electronic components that may be
subjected to electrostatic discharge (ESD). The ESD
diodes connected to the filter ports are designed and
characterized to 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 pro-
tected for contact discharges at greater than
30kV.
This device is particularly well suited for portable elec-
tronics (e.g. mobile handsets, PDAs, notebook comput-
ers) because of its small package format 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 a space-saving, low-profile,
8-lead, 2mm x 2mm TDFN package. It is fabricated
with California Micro Devices' Centurion
TM
process and
available with optional lead-free finishing.

C unless otherwise specified.
Note 2: ESD applied to input and output pins with respect to GND, one at a time.
Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin. For example, if ESD is applied to Pin 1,
then clamping voltage is measured at Pin 8.
Note 4: Unused pins are left open
Note 5: These parameters are guaranteed by design and characterization.
