EMIF04-EAR02M8中文资料2-line EMI filter for earphones + 2-line EMI filter for microphones数据手册ST规格书

描述 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 μQFN-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.

特性 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
• Complies with following standards:
• IEC 61000-4-2 level 4 all pins:
• 15 kV (air discharge)
• 8 kV (contact discharge)

简介

EMIF04-EAR02M8属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的EMIF04-EAR02M8EMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。
