EMI9404
PRAETORIAN) III
4-Channel EMI Array with
ESD Protection
Description
http://onsemi.com
The EMI9404 is an inductor−based (L−C) EMI filter array with
ESD protection, which integrates four filters in a UDFN package with
0.40 mm pitch. Each EMI filter channel of the EMI9404 is

1.8 pF−35 nH–4.7 pF−35 nH– 6 pF. The cut−off frequency at −3 dB
attenuation is 300 MHz and can be used in applications where the data
rates are as high as 160 Mbps, while providing greater than −35 dB
attenuation over the 800 MHz to 2.7 GHz frequency range. The parts
include ESD diodes on every I/O pin and provide a high level of
protection against electrostatic discharge (ESD). The ESD protection
diodes connected to the external filter ports are designed and
characterized to safely dissipate ESD strikes of 14 kV, which is
beyond the maximum requirement of the IEC61000−4−2 international
standard.

(Lower ESD Event)
This device is particularly well suited for wireless handsets, mobile
LCD modules and PDAs because of its small package format and
easy−to−use pin assignments. In particular, the EMI9404 is ideal for
EMI filtering and protecting data and control lines for the LCD display
and camera interface in mobile handsets.
