Description
The EMIF04-EAR02M8 chip is a highly integrated
device designed to suppress EMI/RFI noise for
headset mobile phone. The new LC architecture
on the speaker lines provides a high attenuation
value maintaining a very low serial resistance.
The 8-lead micro-QFN 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.
