Product Overview
The NUF8401MN is an eight-channel (C-R-C) Pi-style EMI filter array with integrated ESD protection. It offers a typical component configuration of R = 100 and C = 12 pF, delivering a cutoff frequency of 175 MHz and stop band attenuation greater than -25 dB from 800 MHz to 2.2 GHz. This performance is ideal for parallel interfaces with data rates up to 117 Mbps, effectively minimizing interference from 2G/3G, GPS, Bluetooth, and WLAN signals. The device integrates EMI/ESD protection in a compact DFN package, providing cost, reliability, and space savings. It is suitable for EMI filtering of LCD and camera data lines, as well as I/O ports and keypads.
