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.
