Product Description
California Micro Devices's CM1423 is an EMI filter
array with ESD protection, which integrates six Pi- fil-
ters (C-R-C) and four channels of ESD protection. The
CM1423’s filters have component values of 12pF-
100Ω-12pF. The part includes ESD protection diodes
on every pin, which provide a very high level of protec-
tion for sensitive electronic components that may be
subjected to electrostatic discharge (ESD).
ESD diodes are designed and characterized to safely
dissipate ESD strikes of ±15kV, beyond the maximum
requirement of the IEC 61000-4-2 international stan-
dard. Using the MIL-STD-883 (Method 3015) specifica-
tion 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 com-
puters) because of its small package format and easy-
to-use pin assignments. In particular, the CM1423 is
ideal for EMI filtering and protecting data lines from
ESD for the Secure Digital (SD) Card interface slot in
mobile handsets. The CM1423 is an all-inclusive solu-
tion for the SD card interface since its EMI filters pro-
vide the proper cut-off frequency to attenuate
unwanted signals.
The CM1423 is manufactured in a space-saving, low-
profile, chip-scale package, and is optionally available
with OptiGuard
also available with lead-free finishing.
