Description
The EMIF02-USB04F3 chip is a highly integrated audio filter device designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interference.
This filter includes ESD protection circuitry, which prevents damage to the protected device when subjected to ESD surges up to 15 kV.

Features
■ EMI symmetrical (I/O) low-pass filter
■ high efficiency in EMI/ESD protection
■ lead-free package
■ very thin package
■ high reliability offered by monolithic integration
■ high reduction of parasitic elements through integration and wafer level packaging

Applications
Where EMI filtering in ESD sensitive equipment is required:
■ mobile phones and communication systems
■ computers, printers and MCU boards
