Integrated EMI and ESD protection solution onsemi NUF4211MNT1G four channel filter for high speed data applications
Product Overview
The NUF4211MN is a four-channel (C-R-C) Pi-style EMI filter array with integrated ESD protection. It features typical component values of R = 100 and C = 8.5 pF, providing a cutoff frequency of 250 MHz and stop band attenuation greater than -20 dB from 800 MHz to 3.0 GHz. This performance makes it ideal for parallel interfaces with data rates up to 167 Mbps in applications requiring minimized wireless interference, effectively reducing interference from 2G/3G, GPS, Bluetooth, and WLAN signals. The device is available in a low-profile 8-lead 2.0 mm x 2.0 mm DFN8 surface mount package, offering an integrated EMI/ESD system solution for cost, system reliability, and space savings. Applications include EMI filtering for LCD and camera data lines, as well as I/O ports and keypads.
