NUF8401MN
8-Channel EMI Filter with
Integrated ESD Protection
The NUF8401MN is an eight−channel (C−R−C) Pi−style EMI filter
array with integrated ESD protection. Its typical component values of
R = 100 and C = 12 pF deliver a cutoff frequency of 175 MHz and
stop band attenuation greater than −25 dB from 800 MHz to 2.2 GHz.
This performance makes the part ideal for parallel interfaces with
data rates up to 117 Mbps in applications where wireless interference
must be minimized. The specified attenuation range is very effective
in minimizing interference from 2G/3G, GPS, Bluetooth® and
WLAN signals.
The NUF8401MN is available in the low−profile 16−lead 1.6 mm x
4.0 mm DFN16 surface mount package.
Features/Benefits
• ±14 kV ESD Protection on each channel (IEC61000−4−2 Level 4,
Contact Discharge)
