Description

The EMIF04-EAR02M8 chip is a highly integrated device designed to suppress EMI/RFI noise for mobile phone headsets. The new LC architecture on the speaker lines provides a high attenuation value maintaining a very low serial resistance.

The ?QFN-8L package offers the possibility to integrate the whole function in a very small PCB space.

Additionally, this filter includes ESD protection circuitry, which prevents damage to the protected device when subjected to ESD surges up 30 kV.
