Product Description
CAMD's CM1425 is an EMI filter array with ESD pro-
tection, which integrates 4 pi filters (C-R-C). The
CM1425 has component values of 20pF-100
-20pF.
The parts include ESD protection diodes on every pin,
which provide a very high level of protection for sensi-
tive electronic components that may be subjected to
electrostatic discharge (ESD). The ESD diodes con-
nected to the filter ports are designed and character-
ized to safely dissipate ESD strikes of
±
15kV, beyond
the maximum requirement of the IEC 61000-4-2 inter-
national 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 CM1425 is
ideal for EMI filtering and protecting data lines from
ESD in wireless handsets.
All CM1425 devices are optionally available with Opti-
Guard
coating which results in improved reliability at
assembly. These devices are also available with stan-
dard and lead-free finishing. The CM1425 is housed in
a space-saving, low-profile, chip-scale package and is
fabricated with California Micro Devices' Centurion
processes.
