Product Description
California Micro Devices's CM1436 is an EMI filter
array with ESD protection, which integrates either four,
six or eight pi filters (C-R-C). Each CM1436 filter has
component values of 15pF-200
Ω
-15pF. These parts
include ESD protection diodes on every pin, providing
a very high level of protection for sensitive electronic
components that may be subjected to electrostatic dis-
charge (ESD). The ESD diodes connected to the filter
ports safely dissipate ESD strikes of
±15kV
contact dis-
charge, twice the specification requirement of the IEC
61000-4-2, Level 4 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 elec-
tronics (e.g. mobile handsets, PDAs, notebook com-
puters) because of its small package and easy-to-use
pin assignments. In particular, the CM1436 is ideal for
EMI filtering and protecting data lines from ESD in
wireless handsets.
The CM1436 is available in space-saving, low-profile,
8-lead, 12-lead and 16-lead 0.4mm pitch TDFN pack-
ages. It is fabricated with California Micro Devices'
Centurion
™
process and available with optional lead-
free finishing.
