LWSON-08 Package EM2374K

4-Channel EMI Filter with Integrated ESD Protection
EM2374K
Description
LWSON-08
The EM2374K is a four-channel (C-R-C) Pi-style EMI filter array
with integrated ESD protection. Its typical component values of
R=100Ω and C=8.5pF deliver a cutoff frequency. This
performance makes the part ideal for parallel interfaces with
data rates up to 70 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 EM2374K is
available in the low-profile 8-lead 1.7mm x1.35 mm LWSON-08
surface mount package.
