Product Description
The CM1636 is an EMI filter array with ESD
protection, which integrates either four, six or eight pi
filters (C-R-C). Each CM1636 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 CM1636 is
ideal for EMI filtering and protecting data lines from
ESD in wireless handsets.
The CM1636 is available in space-saving, ultra-low-
profile, 8-lead, 12-lead and 16-lead 0.4mm pitch
UDFN packages. It is fabricated with California Micro
Devices' Centurion^TM process and available with lead-
free finishing.
