EMIF04-EAR02M8(2009) 데이터시트 - STMicroelectronics

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.

FEATUREs
■ Lead-free package
■ High attenuation: -30 dB at 900 MHz
■ Low cut-off frequencies: 60 MHz for speaker lines
■ High current capability: 50 mA per line
■ Very low PCB space consumption: 1.5 mm x 1.7 mm
■ Very thin package: 0.6 mm maximum
■ High efficiency in ESD suppression IEC6 1000-4-2 level 4
■ High reliability offered by monolithic integration

APPLICATIONs
■ Mobile phones
