CM1485

Dual Channel EMI Filter with ESD Protection

Product Description

Features

•

Two channels of EMI filtering with integrated ESD

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-100Ω-

16pF per channel. The CM1485 has a cut-off fre-

quency 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 MIL-

STD-883 (Method 3015) specification for Human Body

Model (HBM) ESD, the pins are protected for contact

discharges at greater than 30kV.

Applications

•

LCD and Camera data lines in mobile handsets

I/O port protection for mobile handsets, notebook

computers, PDAs etc.

This device is particularly well-suited for portable elec-

tronics (e.g. wireless handsets, PDAs, notebook com-

puters) 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.

•

EMI filtering for data ports in cell phones, PDAs or

notebook computers.

•

Wireless handsets

Handheld PCs/PDAs

LCD and camera modules

The CM1485 is housed in a small, 6-lead SOT-563

package and is available with lead-free finishing.
