CM1425
4-Channel EMI Filter Array
with ESD Protection
Product Description
The CM1425 is an EMI filter array with ESD protection, which
integrates 4 pi filters (C−R−C). The CM1425 has component values of
20 pF − 100 − 20 pF. The parts include ESD protection 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 ±15 kV, well beyond the maximum requirement of the
IEC 61000−4−2 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 ±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 CM1425
is ideal for EMI filtering and protecting data lines from ESD in
wireless handsets.
All CM1425 devices are optionally available with OptiGuardt
coating which results in improved reliability at assembly. These
devices are also available with standard lead−free finishing. The
CM1425 is housed in a space−saving, low−profile, chip−scale package
and is fabricated with the Centuriont processes.
