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-
100

-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 are designed
and characterized to 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 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 CM1405 is
ideal for EMI filtering and protecting data lines from
ESD for the LCD display in mobile handsets.

The CM1405-03 incorporates OptiGuard

coating

which results in improved reliability at assembly and is
available in space-saving, low-profile chip-scale pack-
ages with optional lead-free finishing.

Specifications

Note 1: T

=25

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 A1,

then clamping voltage is measured at Pin C1.

Note 4: Unused pins are left open
Note 5: These parameters are guaranteed by design and characterization.
