NUF4401MN/D
NUF4401MN
4-Channel EMI Filter with
Integrated ESD Protection
The NUF4401MN is a four−channel (C−R−C) Pi−style EMI filter
array with integrated ESD protection. Its typical component values of
R = 200 and C = 15 pF deliver a cutoff frequency of 125 MHz and
stop band attenuation greater than −35 dB from 900 MHz to 2.4 GHz.
This performance makes the part ideal for parallel interfaces with
data rates up to 83 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 NUF4401MN is available in the low−profile 8−lead 2.0 mm x
2.0 mm DFN8 surface mount package.
Features/Benefits
• ±15 kV ESD Protection on each channel (IEC61000−4−2 Level 4,
Contact Discharge)
