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.
