Product Description

The CM1426 is a family of pi-style EMI filter arrays with

ESD protection, which integrates four, six and eight fil-

ters (C-R-C) in a Chip Scale Package with 0.50mm

pad pitch. The CM1426 has component values of

8.5pF-100Ω-8.5pF per channel. The CM1426 has a

cut-off frequency of 230MHz and can be used in appli-

cations where the data rates are as high as 92Mbps.

The parts include avalanche-type 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 ±8kV, 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 dis-

charges at greater than ±15kV.

These devices are particularly well-suited for portable

electronics (e.g. wireless handsets, PDAs, notebook

computers) because of their small package and easy-

to-use pin assignments. In particular, the CM1426 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 CM1426 incorporates Optiguard

improved reliability at assembly. The CM1426 is avail-

able in a space-saving, low-profile Chip Scale Package

with optional lead-free finishing.
