Product Description
California Micro Device's CM1405 is an EMI filter
array with ESD protection, which integrates eight Pi-
filters (C-R-C). The CM1405 has component values
of 25pF-100W-25pF. The parts include avalanche-
type ESD diodes on every pin, which provide 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 •30kV,
exceeding the maximum requirement of the
IEC61000-4-2 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 CM1405 is
ideal for EMI filtering and protecting data lines from
ESD for the LCD display in mobile handsets.
The CM1405-03 incorporates OptiGuardä coating
which results in improved reliability at assembly and
is available in space-saving, low-profile chip-scale
packages with RoHS-compliant, lead-free finishing.
The CM1400-03 incorporates OptiGuard™ coating
which results in improved reliability at assembly. The
CM1400-03 is available in a space-saving, low-profile
chip scale package with RoHS compliant lead-free
finishing.
