NUF4211MN
4-Channel EMI Filter with
Integrated ESD Protection
The NUF4211MN is a four−channel (C−R−C) Pi−style EMI filter
array with integrated ESD protection. Its typical component values of
R = 100 W and C = 8.5 pF deliver a cutoff frequency of 250 MHz and
stop band attenuation greater than −20 dB from 800 MHz to 3.0 GHz.
This performance makes the part ideal for parallel interfaces with
data rates up to 167 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 NUF4211MN is available in the low−profile 8−lead 2.0 mm x
2.0 mm DFN8 surface mount package.
