The CM1483 is an L-C EMI filter array with ESD
protection, which integrates two Pi-filters (C-L-C) for
the headset speaker. The CM1483 has component
values of 100pF-3nH-100pF. The parts include ESD
protection diodes on all input/output pins, which
provide a very high level of protection for sensitive
Applications
? Headset Speaker port in mobile handsets
? I/O port protection for mobile handsets,
notebook computers, PDAs, etc.
? EMI filtering for data ports in cell phones, PDAs
or notebook computers

electronic components that may be subjected to
electrostatic discharge (ESD). The ESD diodes
connected to the filter ports safely dissipate ESD
strikes of ±8kV, beyond the maximum requirement
of the IEC61000-4-2 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
±15kV.
This device is particularly well suited for portable
electronics (e.g. mobile handsets, PDAs, notebook
computers) because of its small package format
and easy-to-use pin assignments. In particular, the
CM1483 is ideal for EMI filtering and protecting
speaker output lines from ESD for the headset
speaker in mobile handsets. Most speakers have
impedance of 8 ? and in order to maximize the
power output, the resistance of an EMI filter needs
to be as low as possible and the CM1483
addresses this by having a C-L-C based EMI filter
where the inductor has less than 1 ? of resistance.
The CM1483 is available in a small, low-profile
(2mm x 2mm) 8-lead TDFN package in a lead-free
finish.
