Product Overview
The NUF2114 is a 2-line audio EMI filter array designed for speaker applications, offering significant EMI filtering and ESD protection. It provides greater than -30 dB attenuation at frequencies from 900 MHz to 3.0 GHz and offers ESD protection by clamping transients from static discharges across all capacitors. This device integrates the functionality of 10 discrete components, simplifying design and reducing board space. It is compliant with IEC61000-4-2 (Level 4) for ESD protection (30 kV contact). Applications include wireless phones, MP3 players, PDAs, digital cameras, and portable DVDs.
