4 and 8-Channel EMI Filter
Arrays with ESD Protection

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 15 pF − 200 W − 15 pF. 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 ±15 kV 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 ±30 kV.

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 WDFN packages. It is fabricated with Centuriont process
and available with lead−free finishing.
