CM1485
Dual Channel EMI Filter with ESD Protection
Features
Product Description
•
The CM1485 is a 2 channel pi-style EMI filter array with
ESD protection, housed in a 6-lead SOT-563 package.
The CM1485 has component values of 16pF-100Ω16pF per channel. The CM1485 has a cut-off frequency of 125MHz and can be used in applications
with data rates up to 48Mbps. The parts include ESD
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 protection diodes safely dissipate ESD strikes of
±15kV, well beyond the maximum requirement of the
IEC61000-4-2 international standard. Using the MILSTD-883 (Method 3015) specification for Human Body
Model (HBM) ESD, the pins are protected for contact
discharges at greater than ±30kV.

•
•
LCD and Camera data lines 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.
Wireless handsets
Handheld PCs/PDAs
LCD and camera modules
This device is particularly well-suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package and easy-to-use
pin assignments. In particular, the CM1485 is ideal for
EMI filtering and protecting data and control lines for
the I/O data ports, LCD display and camera interface in
mobile handsets.
The CM1485 is housed in a small, 6-lead SOT-563
package and is available with lead-free finishing.
