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 20pF-100Ω-20pF.
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 ±15kV, 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 ±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 CM1425 is
ideal for EMI filtering and protecting data lines from
ESD in wireless handsets.
All CM1425 devices are optionally available with
OptiGuard™ coating which results in improved
reliability at assembly. These devices are also
available with standard and lead-free finishing. The
CM1425 is housed in a space-saving, low-profile,
chip-scale package and is fabricated with the
Centurion™ processes.
